The unique luminescent properties and enhanced thermal stability of a novel all-inorganic perovskite CsCaCl₃:Mn²⁺ for solid-state lighting applications

Abstract

This paper addresses the development and characterization of a novel all-inorganic perovskite crystal, CsCaCl3:Mn2+, which presents remarkable potential for advanced white-light LED applications.

Thermodynamic study of CsCaCl3 using neutron diffraction

“…Despite the limited number of data points, the fits converged stably; the determined thermodynamic parameters from these fits are summarised in Table 2. The weighted average value for the Debye temperature is y wD = 304 K, which is higher than that predicted recently from ab initio methods (233.7 K, 30 225.67 K 31 ). However both of these studies assumed cubic symmetry for the material, which may explain the discrepancy.…”
