摘要：mill, with the PVA used as a capping agent. The surface-modiﬁed nanoparticles displayed a near-band-edge photoluminescencewith emission band centered at 428 nmdue to the good su sivation of the nanoparticles by the PVA molecules. An enhancement of the blue emission wa when the nanoparticles were embedded in solid PVA matrix. Elevating the temperature of th nanoparticle solution from 337.5 to 357.5K lead to temperature quenching of the luminesce the decrease of emissive centers caused by desorption of PVA from the nanoparticle surface.
