Аннотация
Nowadays, much attention is paid to the investigation of compounds Re2Zr2O7 with the pyrochlore structure, where “Re” corresponds to La, Ce, Gd, Sm, Nd etc. Such materials are employed in a variety of different applications due to their interesting optical, electrical, magnetic and catalytic properties. A number of different dopants have been studied to obtain visible emissions under IR-excitation. Erbium and ytterbium are one of possible dopants and used to achieve up-conversion luminescence.
