Extraction-pyrolytic synthesis and luminescent properties of europium and terbium polytantalates

Аннотация

The promise of synthesis of europium and terbium polytantalates MTa_xO_y, where М = Eu, Tb; x = 7, y = 19; x = 5, y = 14; x = 3, y = 9 by low-temperature extraction-pyrolytic method has been shown. Luminescent properties of the prepared polytantalates have been assessed from excitation and luminescence spectra at 300 K. The dependence of luminescent characteristics of the studied rare earth metal polytantalates on the temperature and time of precursor pyrolysis has been established.
