Abstract

A few different Sodium borate glasses were made by the melt quenching technique. A sodium borate glass embedded with Dy³⁺ revealed white color when excited by a diode laser. A chromaticity diagram was developed which revealed color coordinates to be x=0.403 and y=0.426 for 375 nm diode laser excitation. A glass that was embedded with Dy³⁺, and Sm³⁺ revealed warm white light under diode laser excitation. However, another glass embedded with Dy³⁺, Sm³⁺, and Tb³⁺ revealed warm white light whose color coordinates are x=0.375 and y=0.455 and the coordinated color temperature is 5173 K.
