The wavelength down conversion approach to solid‐state lighting (SSL) uses down
conversion materials to produce visible light when excited by near‐UV or blue emission from …

Visible blind near-infrared (NIR) photodetection is essential when it comes to weapons used
by military personnel, narrow band detectors used in space navigation systems, medicine …

Hexagonal Yb3+-Ho3+-Tm3+ triply doped NaYF4 nanorods were synthesized via a
hydrothermal method using oleic acid as a stabilizing agent. White up-conversion (UC) …

This review focuses on optical refrigeration with the anti-Stokes fluorescence of rare-earth
(RE)-doped low-phonon micro-and nanocrystals. Contrary to bulk samples, where the …

The phase and crystal structure of Tm3+–Yb3+ codoped Y2WO6 phosphor synthesized via
the solid state reaction method was analysed by X-ray diffraction. The surface morphology …

An experimental and theoretical investigation of the nonlinear transmission coefficient in a
set of Ytterbium-doped silica fibers (YFs) with various concentrations of Yb^ 3+ ions at …

Optical thermometry based on Y 3 Al 5 O 12 (YAG) single crystal optical fiber with end Tm
3+/Yb 3+ co-doped is presented. The YAG crystal fiber with end Tm 3+/Yb 3+ co-doped was …

YAG (Y3Al5O12): Yb3+, Er3+ pure phase nanopowders were prepared by a co-precipitation
method in which ammonium hydrogen carbonate was adopted as precipitator …

The aim of this work is to investigate the effect of annealing and thickness on various
physical properties in Co40Fe40Yb20 thin films. X-ray diffraction (XRD) was used to …

Room-temperature blue and violet upconversion (UC) emissions of Er3+ at 409nm (2H9/2→
4I15/2) and 390nm (4G11/2→ 4I15/2) were observed in Y2O3: Yb3+–Er3+ nanocrystals by …
