While recent studies have demonstrated the high potential of nanophosphors based on the monoclinic Y2O3:Eu3+ (m-Y2O3:Eu3+) for various luminescent applications, the influence of europium concentration on their structural and luminescent properties remains unexplored. In this work, a series of monoclinic Y2O3:Eu3+ nanophosphors with a particle size of ~18 nm and Eu concentrations of 1.5–30 mol% were synthesized for the first time using the laser vaporization method. It was found that the phase composition and morphology of nanoparticles does not depend on the europium content. From a spectroscopic point of view, the optimal Eu concentration for particles of this size is 12 mol%. At this concentration, the PL absolute quantum yield reaches 53 % without additional heat treatment, while CIE color coordinates are (0.65, 0.33). A prototype of pc-LED was fabricated by coating m-Y2O3:Eu3+ nanophosphor on a UV (395 nm) LED chip. The obtained pc-LED spectrum demonstrates that m-Y2O3:Eu3+ is a potential red-emitting phosphor for UV-pumped pc-LEDs, in particular for plant growth LED technology.
