We have investigated spectroscopic properties and energy transfer (ET) of Er 3+ /RE 3+ (RE 3+ = Ce 3+ , Tb 3+ , and Eu 3+ ) codoped Ga 2 O 3 -PbO-Bi 2 O 3 -GeO 2 (GPBG) glass. An intense 1.53-lm emission with a full width at half-maximum (FWHM) of 48 nm and a peak emission cross-section of 1.14 Â 10
