使用 798 nm 激光激发 Tm3++Ho3++Yb3+ 共掺杂亚碲酸盐和锗酸盐玻璃产生白光。这些玻璃在 798 nm 激发下同时产生红、绿和蓝三基色。因此，通过调节 Ho3+ 离子浓度和激发功率，将获得的多色发射调节为白色发光。这些三重掺杂玻璃的紫外激发和荧光光谱会产生额外的发射，而在 798 nm 激发下不会出现这种情况。
White light has been produced using 798 nm laser excitation in Tm3++Ho3++Yb3+ codoped tellurite and germanate glasses. These glasses simultaneously generate the three primary colors, red, green, and blue, on 798 nm excitation. Thus, multicolor emission obtained was tuned to white luminescence by adjusting the Ho3+ ion concentration and excitation power. UV excitation and fluorescence spectra of these triply doped glasses give additional emissions, which do not appear on 798 nm excitation.
