EPR investigation of UV-irradiated single crystals of chromate-doped methylammonium and potassium aluminum alums

Research output: Contribution to journal › Article › peer-review

Abstract

Electron paramagnetic resonance (EPR) has been used to identify and analyze a CrO^3-₄ species produced by UV irradiation in single crystals of chromate-doped methylammonium aluminum alum and in potassium aluminum alum lightly codoped with the methylammonium ion. The photoreduction is a simple reduction of the type CrO^2-₄ + e^- → CrO^3-₄, where the odd electron is a photoelectron liberated by the methylammonium ion.
