THE STUDY OF FLUORESCENT PROPERTIES OF CALCIUM STANNATE CASNO ACTIVATED WITH RARE EARTH METALS
Abstract
A series of prototypes CaSnO3, activated with Yb3+, Er3+, Ho3+, Tm3+ ions, synthesized by solid-phase method. X-ray diffraction analysis of the samples showed the presence of BaSnO3 phase with unit cell parameters characteristic of the orthorhombic crystal. The spectra of the excitation and luminescence spectra of the samples were analyzed. All samples fixed luminescence in the visible spectrum when exposed to exciting radiation in the substance ranges between 260 and 650 nm. In addition, in Yb, Er and Tm samples in a short-range infrared laser irradiation at a wavelength of 811 and 960 nm was detected luminescence which hasn’t been known before.
