Spectroscopic properties in Er3+-doped germanotellurite glasses and glass ceramics for mid-infrared laser materials
Transparent Er3+-doped germanotellurite glass ceramics (GCs) with variable Te/Ge ratio were prepared by controllable heat-treated process. X-ray diffraction (XRD) and transmission electron microscope (TEM) confirmed the formation of nanocrystals in glass matrix. Raman spectra were used to investigate the evolution of glass structure and photon energy. Fourier transform infrared (FTIR) spectra w...
متن کاملSpectroscopic properties and upconversion mechanisms in Er3+-doped fluoroindate glasses.
Fluorindate glasses containing 1,2,3,4 ErF3 mol % were prepared in a dry box under argon atmosphere. Absorption, Stokes luminescence ~under visible and infrared excitation!, the dependence of S3/2, I11/2, and I13/2 lifetimes with Er concentration, and upconversion under Ti-saphire laser excitation at l5790 nm were measured, mostly at T577 and 300 K. The upconversion results in a strong green em...
متن کاملLu3+/Yb3+ and Lu3+/Er3+ Co-doped Antimony Selenide Nanomaterials: Synthesis, Characterization, Electrical, Thermoelectrical and Optical Properties
Lu3+/Yb3+ and Lu3+/Er3+ Co-doped Sb2Se3 nanomaterials were synthesized by a Co-reduction method in hydrothermal condition. Powder XRD patterns indicate that the LnxLn′xSb2-2xSe3 Ln: Lu3+/Yb3+ and Lu3+/Er3+ crystals (x= 0.00-0.04) are isostructural with Sb2Se3. The cell parameters were increased for compounds upon increasing the dopant content (x). SEM and TEM images show that Co-doping of Lu3+/...
متن کاملSpectroscopic properties and energy transfer parameters of Er3+- doped fluorozirconate and oxyfluoroaluminate glasses
Er3+-doped fluorozirconate (ZrF4-BaF2-YF3-AlF3) and oxyfluoroaluminate glasses are successfully prepared here. These glasses exhibit significant superiority compared with traditional fluorozirconate glass (ZrF4-BaF2-LaF3-AlF3-NaF) because of their higher temperature of glass transition and better resistance to water corrosion. Judd-Ofelt (J-O) intensity parameters are evaluated and used to comp...
