Synthesis and Upconversion Spectroscopy of Yb Er Doped M 2 O 2 S ( M = La , Gd , Y ) Phosphors
Yb and Er doped M2O2S (M= Y, Gd, La) phosphor was synthesized by solid state flux fusion method and their up conversion spectral properties were studied as a function different Yb concentrations. The solid state flux fusion results in well crystallized hexagonal shaped phosphor particles of average size 4–6 m. Upconversion spectral studies shows that all the compositions are stronger in green e...
متن کاملAbsolute quantum yield measurements in Yb/Ho doped M2O2S (M=Y, Gd, La) upconversion phosphor
Using the integrating sphere technique the absolute quantum yield measurements of the visible emission bands at 550, 650 and 750 nm in Yb/Ho doped M2O2S (M1⁄4Y, Gd, La) upconversion phosphor have been reported for the first time. Observations show that the 750 nm emission in La2O2S doped with 1 mol% each of Yb and Ho yield the highest efficiency of 0.12% followed by green emission which is 0.06...
متن کاملEnhanced Photovoltaic Performance of Dye-Sensitized Solar Cells by Efficient Near-Infrared Sunlight Harvesting using Upconverting Y2O3:Er3+/Yb3+ Phosphor Nanoparticles
We report the efficiency enhancement in dye-sensitized solar cells (DSSCs) using Er(3+)/Yb(3+)-co-doped Y2O3 (i.e., Y2O3:Er(3+)/Yb(3+)) phosphor nanoparticles, prepared by a simple and cost-effective urea-based homogeneous precipitation method, for efficient near-infrared (NIR) sunlight harvesting. Under the light excitation at a wavelength of 980 nm, the as-prepared samples exhibited strong up...
متن کامل(La0.97RE0.01Yb0.02)2O2S Nanophosphors Converted from Layered Hydroxyl Sulfate and Investigation of Upconversion Photoluminescence (RE=Ho, Er)
Phase-pure (La0.97RE0.01Yb0.02)2O2S upconversion (UC) nanophosphors (average crystallite size ~ 45 nm; RE=Ho, Er) were annealed from their hydrothermally crystallized layered hydroxyl sulfate precursors in flowing hydrogen at 1200 °C for 1 h, with water vapor as the only exhaust. Under 978-nm laser excitation (up to 2.0 W), the Ho3+-doped phosphor exhibited green (medium), red (weak), and near-...
متن کاملSmaller than a nanoparticle with the design of discrete polynuclear molecular complexes displaying near-infrared to visible upconversion.
This work shows that the operation of near-infrared to visible light-upconversion in a discrete molecule is not limited to non-linear optical processes, but may result from superexcitation processes using linear optics. The design of nine-coordinate metallic sites made up of neutral N-heterocyclic donor atoms in kinetically inert dinuclear [GaEr(L1)(3)](6+) and trinuclear [GaErGa(L2)(3)](9+) he...
