Abstract

In this short communication, we present the results concerning the excitation and emission spectra of I mol% EU3+ -doped 50ZnCl(2) + 20BaCl(2) + 29KCI glass. A bright red color emission was observed under an UV source from this glass. The photoluminescence spectra have shown prominent red emission transition (D-5(0) —> F-7(2)) at 610 nm along with three other weak emission transitions of D-5(0) —> F-7(0), (1 and 3) at 580, 598 and 650 Dm upon excitation with six identified excitation bands. Dependence of the emission intensities and lifetimes based on the excitation wavelengths employed has been investigated. (C) 2002 Elsevier Science B.V. All rights reserved.
