Title: Spectroscopy of Mn 4+ in orthorhombic perovskite, LaInO 3

Abstract

The low temperature spectroscopic properties of Mn 4+ (3d 3) in the orthorhombic perovskite, LaInO 3, is examined in this work. The exchange charge model of crystal-field theory is used to calculate the Mn 4+ energy levels. The spectra can be fitted by the parameters D q = 1776 cm –1, B = 700 cm –1 and C = 3189 cm –1, with C/B = 4.5. Discussions pertaining to the low luminescence efficiency of LaInO 3:Mn 4+ are presented. A comparative study of the variations in the energy of the 2E g4A 2g emission transition in a series of materials with the perovskite structure is presented. Here, the data suggest a relationship between the energy of the 2E g4A 2g emission transition and the deviation of the octahedral O-Mn-O bond angle from the ideal 90°. It is concluded that the angular distortion is not large enough to support the development of high luminosity Mn 4+ activated phosphors in the ABO 3 perovskite family of materials.
