Luminescence properties of praseodymium- and erbium-doped silver bromide crystals

摘要

The luminescence of silver bromide crystals doped with praseodymium and erbium ions was investigated over the visible and near-infrared spectral regions. The emission, excitation, and absorption spectra, as well as kinetic parameters, were measured over a bread temperature range. The Judd-Ofelt analysis was used to calculate transition rates, branching ratios, and luminescence quantum efficiencies of rare-earth doped crystals. Good agreement between theoretical and experimental results was obtained. #1997 Optical Society of America
