Luminescent properties of solid solutions BaFe12-xAlxO19		  pdf 

ABSTRACT

The crystal structure and luminescent properties of Al-substituted BaFe12O19 are studied. It is established that under normal conditions the samples are characterized by the space group P63/mmc. BaFe12-xAlxO19 crystals (x = 0.1-1.2) are excited by a laser with wavelengths of 375 nm and 435 nm and their luminescent features are studied. From the obtained luminescent spectra, it is seen that the intensity of the spectra increases at the replacement of magnetic Fe3+ ions by diamagnetic Al3+ ions. During laser excitation by wavelength of 435 nm, anti-Stokes luminescence is observed in the ultraviolet region.

Keywords: multiferroic, crystal structure, luminescence properties.
