Quantum cutting and tunable luminescence properties in Pr3+/Sm3+, Yb3+ co-doped SrMoO4 powders

Highly efficient near-infrared quantum cutting in Ce3+/Yb3+ co-doped chalcohalide glasses

Spectroscopy and 1μm Luminescence by Visible Quantum Cutting in Pr3+-Yb3+ Codoped Glass

The quantum cutting phenomenon of a blue photon into two infrared photons is reported in glass codoped with Pr-Yb ions. Oxyfluoride glass with compositions of 32SrF2-0.1PrF3-2.9YbF3-42SiO2-23Al2O3 were prepared, and photoluminescence properties in the range from visible to near-infrared were investigated. Evidence of several energy transfers, such as (Pr:P0→G4)→(Yb:F5/2←F7/2) and (Pr:D2→F4, F3)...

Upconversion luminescence properties of Yb3+, Gd3+, and Tm3+ co-doped NaYF4 microcrystals synthesized by the hydrothermal method.

Yb3+/Gd3+/Tm3+ co-doped prism-like NaYF4 microcrystals were synthesized through a facile ethylene diamine triacetic acid (EDTA)-assisted hydrothermal method. The microcrystals were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), upconversion (UC) emission spectra, and decay curve. After annealing in an argon atmosphere, the microcrystals emitted bright blue and int...

Lu3+/Yb3+ and Lu3+/Er3+ Co-doped Antimony Selenide Nanomaterials: Synthesis, Characterization, Electrical, Thermoelectrical and Optical Properties

Lu3+/Yb3+ and Lu3+/Er3+ Co-doped Sb2Se3 nanomaterials were synthesized by a Co-reduction method in hydrothermal condition. Powder XRD patterns indicate that the LnxLn′xSb2-2xSe3 Ln: Lu3+/Yb3+ and Lu3+/Er3+ crystals (x= 0.00-0.04) are isostructural with Sb2Se3. The cell parameters were increased for compounds upon increasing the dopant content (x). SEM and TEM images show that Co-doping of Lu3+/...
