Almraet--We have carried out absorption and photoluminescence spectra of six newly prepared TmF3 (2 M%) doped fluorophosphate glasses of composition: (NaPO3)6-BaF2-ZnF2-RF where R = Li, Na, K, (Li-Na), (Na-K) and (K-Li). By evaluating the Judd-Ofelt intensity parameters for the measured absorption
Tm 3+ : GdVO 4 and Ho 3+ : GdVO 4 crystals with good optical quality were grown by Czochralski technique. Polarized absorption and unpolarized fluorescence spectra of Tm 3+ and Ho 3+ in GdVO 4 crystals were measured. The Judd-Ofelt (JO) model was applied to obtain the three phenomenological intensit
A series of Er 3+ -doped 50Bi 2 O 3 -(50-x)B 2 O 3 -xGeO 2 +0.5 wt% Er 2 O 3 (x ΒΌ 0, 5, 10, 15, 20 mol%) glasses were prepared. The thermal stability, absorption spectra, emission spectra and lifetime of the 4 I 13/2 level of Er 3+ ions were measured and studied. It is found that the absorption cros
