  • Publication number: 20110315895
    Abstract: The present invention relates to a luminescent glass element comprising a luminescent glass substrate, which a metal layer is positioned on a surface thereof. The metal layer is provided with a metal microstructure. The luminescent glass substrate has composite oxides represented as the following formula: aM2O.bY2O3.cSiO2.dCe2O3, wherein M represents alkali metal element, a, b, c and d are, by mol part, 25-60, 1-30, 20-70 and 0.001-10 respectively. The present invention also provides a producing method of the luminescent glass element and a luminescing method thereof. The metal layer is positioned on the luminescent glass substrate, thereby improving luminescence efficiency of the luminescent glass substrate. The luminescent glass element can be used in luminescent devices with ultrahigh brightness or high-speed operation.
