Abstract

The authors study how the thermodynamic conditions of the growth of MgAl/sub 2/O/sub 4/-Cr/sup 3 +/ crystals affect their spectroscopic environment of the Cr/sup 3 +/ ions. The absorption spectra of MgAl/sub 2/O/sub 4/-Cr/sup 3 +/ single crystals grown at various speeds is shown. Photoluminescence excitation spectra of MgAl/sub 2/O/sub 4/-Cr/sup 3 +/ crystals measured on the 686-nm luminescence line is also presented. Thermoluminescence curves of the crystals irradiated with UV light and x-ray quanta are given. The thermoluminescence curves support the existence of spatially bound Cr/sup 3 +/-defect pairs.

Synthesis, characterization, photoluminescence and EPR investigations of Mn doped MgAl{sub 2}O{sub 4} phosphors

Journal Article Singh, Vijay; Chakradhar, R; Rao, J; ... - Journal of Solid State Chemistry

MgAl{sub 2}O{sub 4}:Mn phosphors have been prepared at 500 deg. C by combustion route. Powder X-ray diffraction (XRD) indicated the presence of mono-MgAl{sub 2}O{sub 4} phase. Scanning electron microscopy showed that the powder particle crystallites are mostly angular. Fourier transform infrared spectroscopy confirmed the presence of AlO{sub 6} group which makes up the MgAl{sub 2}O{sub 4} spinel. Photoluminescence studies showed green/red emission indicating that two independent luminescence channels in this phosphor. The green emission at 518 nm is due to {sup 4} T {sub 1} {sup {yields}}{sup 6} A {sub 1} transition of Mn{sup 2+} ions. The emission at 650more »« less

Electronic structure of defects in oxides. Final report, December 1, 1979-November 30, 1980. [. cap alpha. -Al/sub 2/O/sub 3/; MgAl/sub 2/O/sub 4/]

Technical Report Summers, G

Details of the electronic structure of F-type centers in the series of oxides SrO, CaO, ..cap alpha..-Al/sub 2/O/sub 3/ and MgAl/sub 2/O/sub 4/ have been determined using measurements of photoconductivity, luminescence, and fluorescence lifetimes. Measurements were made over the spectral range 2 to 6.5 eV and over the temperature range 4 to 350/sup 0/K. The centers were introduced into SrO by electron, on proton or neutron bombardment, into CaO and ..cap alpha..-Al/sub 2/O/sub 3/ by electron a neutron bombardment or thermochemical coloration, and into MgAl/sub 2/O/sub 4/ by particle bombardment.

Color and Luminescence Centers in LuAG and Pr:LuAG Crystals Before and After {sup 60}Co γ-Irradiation

Journal Article Khaiitov, I.; Vil’danov, R.; Amonov, M. - Optics and Spectroscopy

The absorption and thermoluminescence spectra and their relaxation in pure and praseodymium-doped LuAG crystals are comparatively studied to determine the contribution of intrinsic and impurity defects before and after irradiation by {sup 60}Co γ-quanta with an average energy of 1.25 MeV, dose rate of 0.8 Gy/s, and dose of 10{sup 3} Gy at 310 K. The existence of intrinsic F{sup +} defects with a typical absorption band at 375 nm and impurity Cr{sup 4+} centers absorbing at 285, 420, 490, and 595 nm in both LuAG and Pr:LuAG samples before irradiation is related to the crystal-growth technology and the impuritymore »« less
