متن کاملOptical Properties of Ho3+ Doped in Tellurite Glass
We visit the standard procedure for analyzing the optical spectrum of Ho doped tellurite glass has been studied. The glass was formed using a composition 79% Te O2 + 20% Li2 CO2 + 1% Ho O2. I density and refractive index were measured and used to calculate various physical properties such as, rare earth concentration, mean atomic volume, electric polarization, ionic radius, molar refractivity, ...
متن کاملInvestigation of mid-infrared emission characteristics and energy transfer dynamics in Er3+ doped oxyfluoride tellurite glass
Er(3+) doped oxyfluoride tellurite glasses have been prepared. Three Judd-Ofelt parameters Ωt (t=2, 4, 6) and radiative properties are calculated for prepared glasses. Emission characteristics are analyzed and it is found that prepared glasses possess larger calculated predicted spontaneous transition probability (39.97 s(-1)), emission cross section σem (10.18 × 10(-21)cm(2)) and σem × Δλeff (...
متن کاملSpectroscopic 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 کاملA Point Temperature Sensor Based on Upconversion Emission in Er3+/Yb3+ Codoped Tellurite-Zinc-Niobium Glass
Er3+/Yb3+ codoped tellurite-zinc-niobium (TZNb) glass was prepared by the melt-quenching method and used for the construction of a point all-fiber temperature sensor. The glass thermal stability and network structural properties were studied by differential thermal analysis and Raman spectrum, respectively. High glass transition temperature is beneficial to widen the working temperature range. ...
