Kopsavilkums

The low temperature spectroscopic properties of Mn⁴⁺ (3d³) in the orthorhombic perovskite, LaInO₃, is examined in this work. The exchange charge model of crystal-field theory is used to calculate the Mn⁴⁺ energy levels. The spectra can be fitted by the parameters Dq = 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 LaInO₃:Mn⁴⁺ are presented. A comparative study of the variations in the energy of the ²E_g→⁴A_2g emission transition in a series of materials with the perovskite structure is presented. The data suggest a relationship between the energy of the ²E_g→⁴A_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 Mn⁴⁺ activated phosphors in the ABO₃ perovskite family of materials.
