Abstract: An organic light-emitting device includes a first electrode layer, an emission layer, an electron transporting layer, an electron injection layer, and a second electrode layer sequentially formed from bottom to top. The emission layer includes a guest light-emitting material, a first phenyl phosphine oxide derivative and a hole transporting material. The electron transporting layer includes a second phenyl phosphine oxide derivative and a third phenyl phosphine oxide derivative different from the second phenyl phosphine oxide derivative. One of the second phenyl phosphine oxide derivative and the third phenyl phosphine oxide derivative is identical to the first phenyl phosphine oxide derivative. The electron injection layer includes an alkaline metal compound.

Abstract: A field disinfection mobile robot is provided. The field disinfection mobile robot includes a light-emitting device and a mobile device. The light-emitting device includes at least one lamp. The at least one lamp is configured to emit ultraviolet light. The mobile device carries the light-emitting device and includes at least one wheel and a processing circuit. The processing circuit calculates irradiation time according to a level of a lethal dose and intensity of the ultraviolet light and controls a rotation speed of the at least one wheel according to the irradiation time.

Abstract: A method for changing a booting source when a first operating system is being executed is disclosed. The method is utilized in a computer system having a first storage device storing the first operating system and a second storage device storing a second operating system. The method includes: receiving a signal from the second storage device; detecting whether the second storage device is a target device; setting the second storage device as a booting device; rebooting; and executing the second operating system from the second storage device.
