Luminescence of La and Sc impurity centers in YAlO3 single-crystalline films
نویسندگان
چکیده
The luminescence of LaY 3+ and ScY 3+ and ScAl 3+ centers created by lanthanum and scandium ions at Y and Al cation sites of YAlO3 perovskite lattice was investigated. The features of emission of excitons localized at the mentioned centers in YAlO3:La and YAlO3:Sc single-crystalline films were analyzed by means of time-resolved emission spectroscopy and luminescence decay kinetics measurements under excitation by synchrotron radiation at 9 and 300K. r 2007 Published by Elsevier B.V.

Luminescence properties of Y3Al5O12:Ce nanoceramics
Comparative analysis of the luminescent properties of Y3Al5O12:Ce (YAG:Ce) transparent optical ceramics (OC) with those of single crystal (SC) and single crystalline film (SCF) analogues has been performed under excitation by pulsed synchrotron radiation in the fundamental absorption range of YAG host. It has been shown that the properties of YAG:Ce OC are closer to the properties of the SCF co...
متن کاملVisible photoluminescence from porous a-Si:H and porous a-Si:C:H thin films
We report on the influence of doping, temperature, porosity, band gap, and oxidation on the photoluminescence ~PL! properties of anodically etched porous a-Si:H and a-Si:C:H thin films. Only boron-doped, p-type a-Si:H samples exhibited visible photoluminescence. Two broad PL peaks at ;1.6 and ;2.2 eV are apparent in room temperature PL spectra. The intensity of the 2.2 eV peak as well as the na...
متن کاملOptical spectroscopy of single impurity centers in semiconductors.
Using optical spectroscopy with diffraction limited spatial resolution, the possibility of measuring the luminescence from single impurity centers in a semiconductor is demonstrated. Selectively studying individual centers that are formed by two neighboring nitrogen atoms in GaAs makes it possible to unveil their otherwise concealed polarization anisotropy, analyze their selection rules, identi...
متن کاملLuminescence and scintillation characteristics of YAG:Ce single crystalline films and single crystals
The detailed comparative analysis of luminescent and scintillation properties of the single crystalline films (SCF) of YAG:Ce garnet grown from melt-solutions based on the traditional PbO-based and novel BaO-based fluxes, and of a YAG:Ce bulk single crystal grown from the melt by the Czochralski method, was performed in this work. Using the Am (a-particle, 5.49 MeV) excitation we show that scin...
