Frequency upconversion emissions in layered lead–germanate–tellurite glasses for three-color display
نویسندگان
چکیده
This letter is aiming to develop a full-color glass for the three-dimensional and three-color display. The Yb/Tm/Er codoped lead–germanate–tellurite bulk glass has been fabricated and the upconversion emissions have been investigated. The reduced blue and green emission intensity suggests that it is difficult to achieve three-color display in the multiple-rare-earth ions doped glass. Then a two-layer lead–germanate–tellurite glass has been fabricated and the results show that the intensities of upconverted blue and green emissions remain same as emissions in the Yb/Tm and Yb/Er co-doped glasses. 2005 Elsevier B.V.

We investigate the spectroscopic properties of the 1.5-microm emission from the (4)I(13/2)-->(4)I(15/2) transition of Er(3+) ions in bismuth-germanate-lead glasses for applications in broadband fiber amplifiers. The emission peak locates at 1532nm with a full width at half-maximum (FWHM) of approximately 65nm. The measured lifetime and the calculated emission cross-section of this transition ar...
متن کاملThe effect of La2O3 in Tm3+-doped germanate-tellurite glasses for ~2 μm emission
A germanate-tellurite glass (GeO2-TeO₂-K₂O-Nb₂O₅-La₂O₃) with thulium doping has been investigated for application as a laser material around 2.0 μm regions. Under the 808 nm laser diode pumped, intense 1.8 μm emission is obtained. Based on the absorption spectra, radiative properties are predicted using Judd-Ofelt theory. The maximum value of emission cross-section of Tm(3+) around 1.8 μm can r...

In this work, we report the optical properties of Tm ions in tellurite glasses (TeO2-TiO2-Nb2O5) for different Tm 3+ concentrations ranging between 0.05 and 1 wt%. Judd-Ofelt intensity parameters have been determined to calculate the radiative transition probabilities and radiative lifetimes of excited states.

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...
