On the analogy between photoluminescence and carrier-type reversal in Bi- and Pb-doped glasses
Journal Article
carrier-type reversal in Bi- and Pb-doped glasses. Optics express, 21(7), 8101-8115. https://doi.org/10.1364/OE.21.008101

Reaction order in Bi-doped oxide glasses depends on the optical
basicity of the glass host. Red and NIR photoluminescence (PL) bands
result from Bi2+ and Bin clusters, respectively. Very similar centers are
present in Bi- and Pb-doped oxide and ch... Read More about On the analogy between photoluminescence and carrier-type reversal in Bi- and Pb-doped glasses.

Optical and electronic properties of bismuth-implanted glasses
Journal Article

Photoluminescence (PL) and excitation spectra of Bi melt-doped oxide and chalcogenide glasses are very similar, indicating the same Bi center is present. When implanted with Bi, chalcogenide, phosphate and silica glasses, and BaF2 crystals, all displ... Read More about Optical and electronic properties of bismuth-implanted glasses.

We report the compositional dependence of absorption, emission, decay constant and quantum efficiency
(QE) of GeO2:Al2O3:PbO:Bi2O3 glass with the aim of finding the composition most suitable for a laser gain
medium. As the Bi2O3 content was varied... Read More about Compositional dependence of the optical properties of bismuth doped lead-aluminum-germanate glass.
