Abstract

Core–shell-structured La₂O₃:Eu³⁺–La₂Sn₂O₇ nanoparticles were fabricated through SnO₂-coating of LaOF:Eu³⁺ in an aqueous solution and subsequent heat treatments at a higher temperature. The nanoparticles exhibited high chemical stability under an ambient atmosphere and intense red photoluminescence upon irradiation with ultraviolet light.
