The quantum dot composite structure includes: a glass particle including a glass matrix and a plurality of quantum dots located in the glass matrix, wherein at least one of the plurality of quantum dots includes an exposed surface in the glass matrix; and an inorganic protective layer disposed on the glass particle and covering the exposed surface.

Abstract: A connection structure of a spectacle frame includes a frame, a connection member, and a temple. The frame is provided with a joint portion at each of both sides thereof, and a pivot shaft protrudes from each of upper and lower surfaces of a joint end of the joint portion. The connection member includes a body provided with a through-hole and having first and second abutting portions at front and rear sides of the through-hole. A head end of the connection member is provided with two shaft holes to respectively connect the two pivot shafts. The temple has a bending portion and an elastic piece extending from the bending portion and passing through the through-hole, such that the bending portion abuts against the first abutting portion and the second abutting portion to allow the temple relative to the frame to be folded inward or stretched outward.

Abstract: The present disclosure provides a wavelength conversion structure, a light-emitting apparatus, and a display device using the wavelength conversion structures. The wavelength conversion structure includes a porous inorganic shell and a plurality of organic complex phosphor particles filled in the porous inorganic shell. Wherein the plurality of organic complex phosphor particles is capable of being excited to emit light with a peak wavelength in the visible light range.

Abstract: An eyeglass temple on which an accessory device is adapted to be mounted includes a concave portion provided with a plurality of substantially figure 8-shaped jacks abutting and communicating with one another in the lengthwise direction of the eyeglass temple. The accessory device includes a body, a flexible tube connected with the body, and a plug installed at one end of the flexible tube. The plug is detachably coupled with one of the substantially figure 8-shaped jacks. The accessory device can be mounted on the eyeglass temple securely and fixed at an adjustable position adaptively for flexible change of the accessory device and amenity of a pair of eyeglasses worn on a user.

Abstract: An attachment structure for front hanging eyeglasses includes a pair of main eyeglasses, at least one magnetic socket, and a pair of front hanging eyeglasses. The magnetic socket is detachably combined on the main eyeglasses and provided with a first magnet. The front hanging eyeglasses includes an auxiliary eyeglass, a support device, and at least one magnetic connector. The support device includes two supporting portions detachably combined on the main eyeglasses. A shaft is connected between the supporting portions, and a rotary tube is rotatably mounted around the shaft and engaged with the auxiliary eyeglass, so that the auxiliary eyeglass is pivotally rotated about the shaft. The magnetic connector is mounted on the support device and has a second magnet with which the first magnet is engaged, so that the front hanging eyeglasses can be securely hung in the front of the main eyeglasses.

Abstract: The invention relates to a method for synthesizing tetrahydroisoquinoline oxazolidine. The method is carried out at a room temperature between 20° C. and 35° C.

Abstract: A pair of front hanging eyeglasses includes a lens frame and two lenses combined with the lens frame. The lens frame includes a connecting arm and at least one fastening portion. The fastening portion includes an upper portion extending outside from a surface of the connecting arm and an extension portion extending downward from the upper portion. A connecting slot is defined between the connecting arm and the at least one fastening portion. A magnet is provided on the upper portion or the extension portion and located in the connecting slot. The fastening portion is adapted to be hung on an iron spectacle frame, and the magnet is magnetically mounted on the spectacle frame for the pair of front hanging eyeglasses adhering to a pair of eyeglasses with a common iron spectacle frame.

Abstract: A Bluetooth earphone combined with a pair of eyeglasses includes an earphone body and an engaging member. The earphone body includes a recess in which two axle holes and ratchets are designed. The engaging member includes a coupling portion, a ratchet wheel provided at the bottom of the engaging member, and two shafts provided on the ratchet wheel. The shafts are engaged in the axle holes, and the ratchet wheel are coupled with the ratchets, such that the engaging member can rotate at a proper angle relative to the earphone body with the shafts as a center of rotation and can be sustained in an adequate angle. As such, the Bluetooth earphone is flexibly combined with a pair of eyeglasses owned by a user in usage.

Abstract: A pair of eyeglasses includes a spectacles frame and two temples. The spectacles frame has a mounting adapter at each lateral end thereof. A pivot hole and two engaging holes are provided in the mounting adapter. A front end of each temple is provided with two connecting rods and a pivot shaft formed at outer ends of the connecting rods. The pivot shaft is held inside the pivot hole of a corresponding mounting adapter to allow each temple relative to the spectacles frame to be pivoted between a folded position and an extended position. When the temple is at the folded position, the connecting rods are separated from the engaging holes such that the temple can be detached from the spectacles frame. When the temple is at the extended position, the connecting rods are held and positioned inside the engaging holes.

Abstract: A magnetically mounted connector is used to join a spectacles frame and a temple of a pair of eyeglasses. The spectacles frame has a mounting portion at each lateral end thereof. The magnetically mounted connector includes a connector body, a magnetic holder, and a magnet held in the magnetic holder. The connector body has one end to which the mounting portion of the spectacles frame is connected. The magnetic holder is extended outward from the connector body. When the magnetically mounted connector joins the spectacles frame and the temple, the magnet is situated at an inner side of the mounting portion of the spectacles frame for adhesion of a pair of auxiliary eyeglasses to the pair of eyeglasses.
