摘要: Abstract The luminescent properties of Eu 3+ -doped porous glass were investigated and reduction to 2+ was observed when the glasses heat treated in air. absorption, emission excitation spectra measured results significantly depended on treating temperature. integral intensity ions at different temperatures also investigate this process. Electron spin resonance (ESR) samples measured, which confirmed effect. A possible mechanism discussed explain
