Phase Equilibria in Ternary System CsBr-AgBr-InBr(3)

The double perovskite halides A(2)B(I)B(III)X(6) provide flexibility for various formulation adjustments and are of less toxicity in comparison with well-discussed complex lead halide derivatives. Such type of structure can be formed by replacing two Pb(2+) ions in the cubic lattice with a pair of n...

Sumario:The double perovskite halides A(2)B(I)B(III)X(6) provide flexibility for various formulation adjustments and are of less toxicity in comparison with well-discussed complex lead halide derivatives. Such type of structure can be formed by replacing two Pb(2+) ions in the cubic lattice with a pair of non-toxic heterovalent (monovalent and trivalent) metal cations, such as silver and indium. The aim of this work is to briefly characterize the phase equilibria in the ternary system CsBr-AgBr-InBr(3) and investigate the thermodynamic availability of synthesis of Cs(2)AgInBr(6) double perovskite phase by solid-state sintering or melt crystallization. The results demonstrate the unfeasibility of the Cs(2)AgInBr(6) phase but high stability of the corresponding binary bromides perspective for optoelectronics.
