摘要: Samarium doped CdWO4 (Sm-CdWO4) thin films were synthesized by pulsed laser deposition (PLD) using pressed powder targets composed of Sm2O3, CdO, and WO3 mixtures. Congruent, stoichiometric, crystalline obtained on glass substrates at 873 K with 0.01 at. % Sm. The x-ray activated photoluminescence (x-ray PL) spectra redshifted about 40 nm 298 K. Changes the PL component 2.85 eV into those 2.20 2.52 typical in their convolutions. These components showed very similar dependencies excitation wavelengths, indicating that CdWO4 related emissions Sm-doped PLD are relaxed from same midband excited state. peaks characteristic to Sm3+ had two sidebands shifted both lower higher energy sides as much 0.03 eV. Plume emission analyzed elucidate effects Sm our processes. It was interpreted transfer should occur between neutral Cd state laser...
