Abstract
Luminescent properties of , single-doped and codoped sodium silicate glasses were systematically investigated by excitation spectra, emission spectra, and decay curves. Due to the efficient energy transfer from pairs to , varied hues from green to yellowish white and eventually to orange were generated by tuning the content of . A perfect white-light emission with CIE coordinates was realized in , and codoped samples. Our research indicates the potential application of , codoped sodium silicate glasses for converting phosphors for UV LED chips to generate white LEDs.
