Popis: | We report the ESR of Nd3+ in BaTiO3 and derive the electronic structure of its groundstate. – Among the light induced charge conversions found with ESR in nominally undoped BaTiO3 crystals hole photoionization of Fe4+ is the most important. The process is increased by oxidizing the crystals. Some of the holes are trapped as O− next to an unidentified acceptor. The trapping site of the remaining holes is ESR-silent. |
