Extraction-pyrolysis synthesis and luminescence properties of europium polyniobates

Аннотация

The promising character of the synthesis of europium polyniobates (EuNb₃O₉ and EuNb₅O₁₄) by the extraction-pyrolysis method has been demonstrated. The luminescence properties of the synthesized polyniobates have been estimated from excitation and luminescence spectra at 300 K. The dependence of luminescence characteristics of the rare-earth elements polyniobates under study on the temperature and duration of precursor pyrolysis has been established.
