White light glass and preparation method thereof

InactiveCN101857363AHigh fluorescence intensityWide excitation and emission wavelengthsManganese oxideColor temperature
The invention relates to a white light glass and a preparation method thereof, in particular to a white light glass with tin oxide and manganese oxide as light emitting centers and a preparation method thereof. White light illumination plays an important role in daily production and living, but the existing white light illumination has low efficiency, complicated process and difficult miniaturization. Under the condition, the research on the white light glass is taken seriously because the white light glass has the advantages of simple preparation, high luminous efficiency, easy color temperature regulation and the like. Currently, the researches focus on the white light glass doped with rare earth, but rare earth light emission can generate quenching at high concentration, and the lighting peak position can shift along with the use time so as to cause color temperature change. The white light glass with the tin oxide and the manganese oxide as the light emitting centers can make up the shortcomings. The tin oxide and the manganese oxide belong to network intermediates, can be introduced at high concentration, and have higher luminous intensity and conversion efficiency. Simultaneously, the tin oxide and the manganese oxide adopt wide spectrum lighting, and the compounded white light color temperature basically does not change along with time.
