LaInO3-based phosphors activated with rare-earth ions were synthesized and their properties were investigated. New red and green oxide phosphors were found, that could be prospective for w-LED fabrication. It was found that chromium (III) ion works as a sencitizer for Pr3+and Nd3+ ions in LaInO3-based phosphors increasing resulting photoluminescence intensity by 40–90% and 50–80%, ...
