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+/...

متن کاملInfluence of Doping and Excitation Powers on Optical Thermometry in Yb3+-Er3+ doped CaWO4
Optical thermometry has been widely studied to achieve an inaccessible temperature measurement in submicron scale and it has been reported that the temperature sensitivity depends mainly on host types. In this work, we propose a new method to improve the optical temperature sensitivity of Yb3+-Er3+ co-doped CaWO4 phosphors by doping with Li+, Sr2+, and Mg2+ ions and by controlling excitation po...

A fast and versatile fabrication method for high Q milled microrod resonators, directly on rare-earth doped fibers, is demonstrated using a pulsed CO2 laser. Evanescently pumped WGM microlaser with ~9μW output power has been achieved. OCIS codes: (140.3460) Lasers; (140.4780) Optical resonators; (060.2310) Fiber optics; (230.3990) Micro-optical devices
متن کاملOptical and EPR properties of BaY2F8 single crystals doped with Yb
Yb doped materials have turned out to be relevant for efficient high-power continuous-wave lasers, up to the kilowatt class. In the present paper we analyze optical and EPR properties of BaY2F8:Yb (5wt.%) single crystals obtained using Czochralski method. The Yb energy levels for the crystal are as follows: F7/2 (0, 216, 430, 530 cm), F5/2 (10277, 10395, 10735 cm ). BaY2F8 highly doped with Yb ...
