Excitation and photoluminescence spectra of solid solutions based on lanthanum indate with perovskite structure doped by Pr<sup>3+</sup>, Nd<sup>3+</sup>, Cr <sup>3+</sup> ions
Excitation and photoluminescence spectra of La0,997Pr0,003InO3, La0,98Nd0,02InO3, La0,977Pr0,003Nd0,02InO3, La0,977Pr0,003Nd0,02In0,99Cr0,01O3, LaIn,099Cr0,01O3 solid solutions have been studied. It has been found that Cr+ ions incorporated into the In3++ sublattice of La0,977Pr0,003Nd0,02In0,99Cr0,01O3 solid solution can act as Nd3+ photoluminescence sensitizers under the excitation by visible light (λ = 445 nm).
