A light-emitting device includes a semiconductor stack including a first semiconductor layer, a second semiconductor layer, and an active layer emitting an UV light, formed between the first semiconductor layer and the second semiconductor layer; a first transparent conductive layer formed on the second semiconductor layer, the first transparent conductive layer including metal oxide; and a second transparent conductive layer formed on the first transparent conductive layer, the second transparent conductive layer including graphene, wherein the first transparent conductive layer is continuously formed over a top surface of the second semiconductor layer, the first transparent conductive layer comprises a thickness smaller than 10 nm.

Light-emitting device

The present invention relates to a phosphor, a method for preparing the phosphor, an optoelectronic component, and a method for producing the optoelectronic component. The phosphor has the following general formula: LaGaGeO: 3xA, yCr, 5zB, where x, y, and z do not equal to 0 simultaneously; A represents at least one of Gd and Yb; B represents at least one of Sn, Nb, and Ta. For the phosphor, its emission spectrum is within a red visible light region and a near-infrared region when excited by blue visible light, purple visible light or ultraviolet light; and it has a wide reflection spectrum and a high radiant flux. Therefore, it can be used in optoelectronic components such as LEDs to meet requirements of current medical testing, food composition analysis, security cameras, iris/facial recognition, virtual reality, gaming notebook and light detection and ranging applications.

This invention discloses a wavelength converting material. The wavelength converting material comprises a metal haloaluminate compound phosphor with a chemical formula MAlOX:R, wherein M is at least one element selected from the group of Be, Mg, Ca, Sr, Ba and Zn; X is at least one element selected from the group of F, Cl, Br, and I; R is one or more elements selected from the group of the transition metals and at least one element selected from the lanthanide series. Because the emitting wavelength of the metal haloaluminate compound phosphor is 550&#x2dc;650 nm which is from the green to the red light spectrum, the white light mixed by the converted light of the metal haloaluminate phosphor and the blue light has better color rendering index. Besides, this invention also discloses the optoelectronic devices comprising the metal haloaluminate compound phosphor.
