Abstract
The effects of bismuth doping content and temperature on the absorption property and
near-infrared (NIR) luminescence of Bi-doped La2O3-Al2O3-SiO2 (LAS) glasses are presented. The
emission intensity reaches the maximum when the Bi2O3 content in 3.0Bi-LAS is 1.83%. The emission
spectra reach their peaks at 1 190 and 1 117 nm, with full-width at half-maximum (FWHM) values of
330 and 228 nm under 500 and 700-nm excitations, respectively. As the Bi2O3 content increases, the
peak wavelengths and FWHMs of emission bands increase, but their lifetimes decrease. The lifetime of
2.0Bi-LAS is 460 ?s at 9 K, and is almost temperature independent until 350 K. The NIR emission of
Bi in the system has strong resistance to thermal quenching from 9 to 350 K.
