Tailoring multiphonon relaxation and cross relaxation energy transfer in mixed ionic-electronic 20Li(2)O-xBi(2)O(3)-(78-x)TeO2-1Er2O3-1Ag glasses at NIR region

A glass composed of 20Li2O-xBi2O3-(78-x)TeO2-1Er2O3-1Ag was fabricated by melt–quenching method to examine the influence of mixed ionic–electronic (MIE) effect on AC conductivity (AC) and photoluminescence properties. The AC decreased as the Bi2O3 content increased, until a minimum AC at x=11 mol% a...

Q Science (General) A glass composed of 20Li2O-xBi2O3-(78-x)TeO2-1Er2O3-1Ag was fabricated by melt–quenching method to examine the influence of mixed ionic–electronic (MIE) effect on AC conductivity (AC) and photoluminescence properties.
