We report near infrared broadband emission of bismuth-doped barium-aluminum-borate glasses. The broadband emission covers 1.3microm window in optical telecommunication systems. And it possesses wide full width at half maximum (FWHM) of ~200nm and long lifetime as long as 350micros. The luminescent properties are quite sensitive to glass compositions and excitation wavelengths. Based on energy m...

A lithium bismuth borate glass system is prepared by the conventional melt quenching technique. The Powder X-Ray diffraction analysis of the prepared samples confirms the amorphous nature of the samples. The density and molar volume studies report the change of structure with the increase of bismuth content. The FTIR analysis of the samples revealed that the network structure of the prepared sa...
