2 μm emission properties and nonresonant energy transfer of Er3+ and Ho3+ codoped silicate glasses
2.0 μm emission properties of Er3+/Ho3+ codoped silicate glasses were investigated pumped by 980 nm LD. Absorption spectra were determined. Intense mid-infrared emissions near 2 μm are observed. The spectral components of the 2 μm fluorescence band were analyzed and an equivalent model of four-level system was proposed to describe broadband 2 μm emission. Low OH- absorption coefficient (0.23 cm...
متن کاملStudy of broadband near-infrared emission in Tm3+-Er3+ codoped TeO2-WO3-PbO glasses.
In this work, we report the near-infrared emission properties of Tm(3+)-Er(3+) codoped tellurite TeO(2)-WO(3)-PbO glasses under 794 nm excitation. A broad emission from 1350 to 1750 nm corresponding to the Tm(3+) and Er(3+) emissions is observed. The full width at half-maximum of this broadband increases with increasing [Tm]/[Er] concentration ratio up to a value of ~ 160 nm. The energy transfe...
متن کاملSpectroscopic properties of the 1.4 μm emission of Tm ions in TeO2-WO3-PbO glasses
In this work, we report the spectroscopic properties of the infrared H4→F4 emission of Tm ions in two different compositions of glasses based on TeO2, WO3, and PbO for three Tm2O3 concentrations (0.1, 0.5, and 1 wt%). Judd-Ofelt intensity parameters have been determined and used to calculate the radiative transition probabilities and radiative lifetimes. The infrared emission at around 1490 nm ...
متن کاملHighly efficient mid-infrared 2 μm emission in Ho/Yb-codoped germanate glass
This work reports the mid-infrared emission properties around 2 μm in Ho/Yb codoped germanate glasses. The glass not only possesses good chemical durability and good thermal stability but also has high midinfrared transmittance around 2 μm (90%). In addition, the glass possesses considerably low OH content (20.45 ppm) and large spontaneous transition probability (103.38 s) corresponding to the ...
متن کاملOptical spectroscopy of lanthanide ions in ZnO-TeO2 glasses.
Zinc tellurite glasses of compositions 19ZnO-80TeO2-1Ln2O3 with Ln = Eu, Er, Nd and Tm were prepared by melt quenching. The absorption spectra were measured and from the experimental oscillator strengths of the f-->f transitions the Judd-Ofelt parameters ohm(lambda) were obtained. The values of the ohm(lambda) parameters are in the range usually observed for oxide glasses. For Nd3+ and Er3+, lu...
