  • Patent number: 10734557
    Abstract: A light-emitting device includes a package structure and a light-emitting chip. The package structure has a light exiting surface, a rear surface facing away from the light exiting surface, a groove inward recessed on the rear surface, and an outer surrounding side wall surrounding the groove. The light-emitting chip is disposed in the groove. The width of the package structure gradually decreases from the light exiting surface to the rear surface. The width of the groove gradually increases from inside to outside of the groove.

  • Publication number: 20200190704
    Abstract: The present invention discloses a method for preparing inverse opal photonic crystal fibers. In this method, by means of vertical deposition of colloidal spheres (micron scale or nanoscale), of polystyrene shell-core structured spheres and silica particles, the inverse opal colloidal crystal fiber stripes having a length of about 3.5 cm as well as an adjustable width and thickness is obtained. The invention provides a convenient method and achieves inverse opal photonic crystal fiber stripes with a high yield and a controllable size, and there is no crack on the surface of the fibers or inside the fibers. Furthermore, the inverse opal photonic crystal stripes of the invention can be peeled off from the surface of a glass slide and used conveniently.
