摘要
Quantum leap: Very high quantum yields, thought to be impossible for nanocrystalline phosphor materials, were achieved with CePO 4:Tb/LaPO4 core-shell nano-particles (see picture). Because the LaPO4 shell reduces energy losses at the particle surface, transparent colloidal solutions of these 8-nm particles are highly photoluminescent.
