Band Gap and Diameter Modulation of Quantum Dots in Glasses
Source abstract
Abstract
Modulation of the band gap energy and diameter of quantum dots ( QD s) formed in glasses is important to achieve the optimized performance for applications as infrared light sources, lasers, saturable absorbers, etc. Absorption and photoluminescence of PbS QD s were extended into mid‐infrared wavelength range in glasses containing small amount of lead but oversaturated with sulfur. Dual‐band photoluminescence of PbSe QD s was prepared in oxyfluoride glass‐ceramics containing BaF 2 nanocrystals. By introducing SnO in the glasses, alloyed Pb 1‐ x S n x Se QD s with smaller band gap energies were formed in glasses, and mid‐infrared photoluminescence of Pb 1‐ x S n x Se QD s at ~2570 nm in wavelength was achieved.
