Spectroscopic properties of Er3+-doped antimony oxide glass

Abstract

International audienceSpectroscopic properties of Er3+ ions have been studied in the 60Sb2O3-20WO3-19Na2O-1Bi2O3 (SWNB) glasses doped with 0.25 and 0.50 mol% Er2O3 respectively. The Judd-Ofelt parameters measured from the absorption spectra have been used to calculate the radiative life-time (τr) and the stimulated emission cross section. The low phonon energy, a reduced quenching effect and a high quantum efficiency of 90% for the 1.53 μm expected laser emission into pumping at 980 nm are in favor of promising material laser application

New Er3+ doped antimony oxide based glasses: Thermal analysis, structural and spectral properties

“…An antimony oxide glass as host glass network presents advantages compared to germanate, phosphate or silicate glasses [12].…”

“…Note that the presence of bismuth Bi 2 O 3 in our glasses reduces the χ factor, indicating its important role in the dynamics of fluorescence for SNB2 glass. We compared the parameters obtained in SNB2 glass with those found in other materials [12,31,56], which are illustrated in Fig.6. We can also show that in our experience, there is a clear correlation between the composition of the glass and some spectroscopic quantities.…”

“…The research has mainly focused on oxide glasses, the materials of choice for use in telecommunications wavelengths (1.3 and1.55 µm) [1][2][3][4][5][6][7][8][9][10][11][12]. Rare earth (RE) doped glasses have been key materials for the telecommunication industry, and RE ions such as Er 3+ have attracted much interest as luminescence centers in crystals and glasses.…”

“…Rare earth (RE) doped glasses have been key materials for the telecommunication industry, and RE ions such as Er 3+ have attracted much interest as luminescence centers in crystals and glasses. Currently, special attention is given to the erbium ion due to its emission band at 1.53µm [12][13][14][15][16][17][18][19][20][21][22], which makes it an ideal component for applications in the field of optical data transmission. However, we realize that these oxide glasses, including borate, phosphate and silicate, specifically, have some limits.…”

Spectroscopic properties of Bi2ZnOB2O6 single crystals doped with Pr3+ ions: Absorption and luminescence investigations

“…They are widely employed in solid-state lasers [1,2], scintillators [3], fluorescent lamps [4], optical amplifiers for fiber-optic communication [5], 3D displays [6] and optical frequency converters [7]. Applications of materials activated with RE ions (crystals, optical glasses, optical polymer fibers) in various optoelectronic devices are based on the emission of those ions ranging from the near ultraviolet (UV) and visible (VIS) up to near infrared (NIR) spectral domains [8][9][10][11].…”
