Giant enhancement of phonon-assisted one-photon excited frequency upconversion in a Nd3+-doped tellurite glass
(2013-02-07)
Changing the sample's temperature from 200 K to 535 K, we observed 670-fold enhancement of a phonon-assisted upconversion emission at ≈754 nm obtained from a Nd3+-doped tellurite glass excited by 5 ns laser pulses at 805 ...
Enhancement of spectroscopic and luminescence properties of Er3+ doped tellurite glasses by adding P2O5 for lasing materials
(2018-02-01)
Er3+-doped phosphor-tellurite glasses has been synthesized by conventional melting method. Results of differential scanning calorimetry (DSC) measurements indicate a good thermal stability of tellurite glasses. The DSC ...
Photoluminescence and Structural Analysis of Er3+/Yb3+/Tm3+ Triply Doped Gd2O3
(Brazilian Chemical Soc, 2017-01-01)
Spectroscopic and structural properties of Er3+:Yb3+:Tm3+ triply doped Gd2O3 nanocrystals were investigated. The effect of heat treatment at 800, 900, 1000 and 1100 degrees C for 4h, on the luminescence and the energy ...
Study of Er3+ fluorescence on tellurite glasses containing Ag nanoparticles
(2011-04-12)
Optical characteristics of tellurite glasses containing silver nanoparticles (NPs) and the influence on the emission spectrum of Er 3+ ions were studied. The transitions 4f ↔ 4f from erbium ions, mainly the 4I13/2 → 4I15/2 ...
