▎ 摘　　要

NOVELTY - Photoelectric glass, comprises a light-emitting point and a matrix, where the 20-40% luminescent points are dispersed in the matrix; the luminescent point is a graphene quantum dot material, and the substrate is an aluminoborosilicate glass-ceramic. USE - The photoelectric glass is useful for light emitting device. ADVANTAGE - The photoelectric glass improves the luminous efficiency and luminous uniformity of high-power white light lighting devices, exhibits more excellent mechanical strength, thermal stability and corrosion resistance, improves the luminous stability of the device, and solves the problem of luminous flux attenuation, decreased stability and color coordinate drift. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparation method of the photoelectric glass; and a light emitting device.
