Luminescence dating studies of YeAYilova Hoyuk
(DEC)Ceramic findings collected from YeAYilova Hoyuk located in Izmir were dated using the thermoluminescence dating technique. The area is of significant archaeological importance since it is the first prehistoric settlement ... -
Luminescence from copper nanoparticles
(SEP)The presence of copper nanoparticles in alumina and silica modifies their luminescence, and the changes in spectra are influenced by variations in the nanoparticle size distributions. Luminescence signals are sensitive to ... -
Luminescence of dysprosium doped strontium aluminate phosphors by codoping with manganese ion
(JAN 15)The authors report here the luminescence properties of strontium aluminate doped with dysprosium and manganese. The dysprosium, manganese co-doped powders were prepared by a solid state reaction at temperatures at 1600 ... -
Luminescence of levitated Zr-Ba-La-Al-Na fluoride glass
(SEP 1)Radioluminescence, cathodoluminescence, and thermoluminescence of Zr-Ba-La-Al-Na (ZBLAN) fluoride glass reveal different aspects of the intrinsic imperfections and impurities which control the emission. Except for weak ... -
Luminescence properties of Tb implanted ZnO
(NOV 1)ZnO [0 0 0 1] crystals were irradiated at room temperature with Tb+ ions of 400 keV with fluences from 1 x 10(16) to 2 x 10(17) cm(-2). The implanted layer was examined by several methods, including radioluminescence (RL), ... -
Luminescence studies of zinc borates activated with different concentrations of Ce and La under x-ray and electron excitation
(SEP)Several ZnB2O4 powder samples having dopants concentrations of 0.1, 0.01, 0.04 wt% Ce and La were prepared using the nitric acid method via the starting oxides. Several complementary methods such as powder X-ray diffraction ... -
