Abstract
We synthesize continuous solid solutions with monophasic zircon-type
structure of vanadates of formula YxBi0.95-xVO4:0.05Dy3+ (x = 0-0.95) using a
combined method of co-precipitation and hydrothermal synthesis. The X-ray
diffractometer patterns confirm the formation of a solid solution of
YxBi0.95-xVO4:0.05Dy3+, and the results show that all the samples have monophasic
zircon-type structure. The absorption spectra of the prepared phosphors show a
blue-shift of the fundamental absorption band edge with increasing Y3+ content. An
intense tunable characteristic emission of Dy3+ is observed with the increasing
ratio of Y/Bi. Finally, the mechanism of luminescence of Dy3+ in the
YxBi0.95-xVO4:0.05Dy3+ (x = 0-0.95) solid solution is analyzed and discussed.
