As a result of development of the technology, analysis, organization and synthesis of the research results obtained by the following: (a) found that with increasing of Pr concentration in SrTiO3:Pr3+ up to 10 mol.% the PL spectra became worse by increasing of the intensity of the secondary bands; b) confirmed that an optimal Pr concentration is 0.2 mol.%; (a) found that by crushing the powders in a nitrogen atmosphere leads to increase in brightness to 20%; (d) determined the opportunity of reducing the annealing time of films SrBi2 (Tax Nb1-x) 2O9, which are the basis of ferroelectric structures; (e) obtained nanodispersed cathodophosphor SrTiO3: Pr3 +, Al with high, increased to 1840 cd / m2 brightness of cathodoluminescence.
