Title:
白光を発射する透明ガラスセラミック及びその調製方法
Document Type and Number:
Japanese Patent JP5460923
Kind Code:
B2
Abstract:
A transparent glass ceramic emitting white light and preparation method thereof are provided. The chemical formula of the transparent glass ceramic is aSiO 2 ·bAl 2 O 3 ·cNaF·dCeF 3 ·xDyF 3 , wherein a, b, c, d, and x are mole fractions, a is 35¼50, b is 15¼30, c is 5¼20, d is 5¼20, x is 0.01¼1, and a+b+c+d=100. The transparent glass ceramic can be substituted for the combination of epoxy resin or silica gel and fluorescent powder to seal LED. The transparent glass ceramic has strong excitation spectrum with broadband at ultraviolet area, and can emit strong white light under the excitation of ultraviolet light.
