A study on the luminescent properties of red-emitting praseodymium-activated SrIn2O4 phosphors

Abstract

The photoluminescent (PL) properties of new red-emitting praseodymium-activated strontium indates have been investigated. A series of SrIn2O4:xPr(3+) (x = 6.25 x 10(-4), 0,5%, 2%, and 4%) phases were synthesized and found to exhibit red emission. With different levels of Pr3+ doping, the absolute brightness, CIE chromatic characteristics, PL and cathodoluminescence spectra, and luminescence decay lifetime (tau (R)) for SrIn2O4:xPr(3+) have been systematically investigated. The results are reported and their implications are discussed. (C) 2001 Academic Press.
