Using a solid-phase method, single-phase solid solutions of La1–x Nd x InO3 (x = 0.007, 0.02, 0.05), LaIn0.99Cr0.01O3, and La0.95Nd0.05In0.995Cr0.005O3 have been obtained and their excitation and photoluminescence (PL) spectra have been studied at room temperature. It is found that the intensity of excitation and PL bands for La1–x Nd x InO3 solid solutions depends on the degree of the substitution of La3+ ions by Nd3+ ions. A solid solution with 0.02 < x < 0.05 possesses the largest intensity of the PL bands in IR wavelength range of 850–950, 1040–1100, and 1350–1370 nm. It is found that replacing 0.5% of In3+ ions in a solid solution of La0.95Nd0.05InO3 by Cr3+ ions leads to a substantial increase in the intensity of all the PL bands by exciting with light of the wavelength of λexc = 490 nm and a decrease in the intensity of all the PL bands by an excitation with light of the wavelengths of λexc = 358, 532, and 585 nm.
