Marchylo O. M. Investigation of luminescent properties inherent to SrTiO3:Pr3+ luminophor with Al impurity [Електронний ресурс] / O. M. Marchylo, L. V. Zavyalova, Y. Nakanishi, H. Kominami, A. E. Belyaev, G. S. Svechnikov // Semiconductor physics, quantum electronics & optoelectronics. - 2011. - Vol. 14, № 4. - С. 461-464. - Режим доступу: http://nbuv.gov.ua/UJRN/MSMW_2011_14_4_18 The red-emitting SrTiO3:Pr<^>3+,Al luminophors that can be used for the white light emitting diodes (LEDs) were prepared using the sol-gel method. The starting materials were SrCl2, Ti (O - i - C3H7)4, <$E roman {Al(NO sub 3 ) sub 3~cdot~9H sub 2 O}> and PrCl3. The reaction between them results in a mixture of compounds that transform into single-phase SrTiO3:Pr<^>3+,Al after annealing in air. Displacement of Ti out of the SrTiO3 lattice caused by substitution with Al and formation of individual crystalline TiO2 phase (rutile) were observed. PL spectra show the high-intense red peak (<$E lambda~=~617> nm), the same high-intense peak with the full width at half maximum (FWHM) 20 nm was found in cathodoluminescence spectra. The increase of the aluminium concentration from 0 up to 15 mol.% leads to approximately two-fold increase in the luminance. The latter increases from 180 up to 350 cd/m<^>2 at the anode voltage 10 kV and current density 30 <$E mu roman {A "/" cm sup 2}>.
