摘要: The influence of the cationic sites on luminescent properties Eu3+ in Gd2BaZnO5 has been investigated by site-selective laser excitation and emission spectroscopy along with luminescence decays. It revealed that ions occupy two sites. Stark energy levels at different were assigned from selectively excited spectra 10 K. transfer between crystallographic centers is detected discussed. Excitation spectrum UV region UV-excited also performed, which indicate an efficient transfers host directly Gd3+ to Gd2BaZnO5.
