Abstract

The photoluminescent (PL) properties of new red-emitting praseodymium-activated strontium indates have been investigated. A series of SrIn2O4:xPr3+ (x=6.25×10-4, 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 (τR) for SrIn2O4:xPr3+ have been systematically investigated. The results are reported and their implications are discussed.
