Luminescence and charge trapping in Cs2HfCl6 single crystals: optical and magnetic resonance spectroscopy study
Original language description
Photoluminescence spectra and decays were measured in the extended temperature range of 8-500 K and approximated by a phenomenological model. Self-trapped exciton and defect-related emissions were clearly distinguished with the onset of thermal quenching, above the room temperature. Electron paramagnetic resonance experiment revealed the formation of two configurations of V-k center (Cl-2(-) molecular ion) at low temperatures. One of the V-k centers is created by a hole self-trapping at two neighboring Cl ions. In the temperature range 70-80 K, this state is thermally disintegrated and reappears in another configuration formed most probably by an interstitial Cl ion.
