摘要	Photoluminescent properties of zero-dimensional LaPO4:Eu nanoparticles (NPs) and one-dimensional nanowires (NWs) prepared by the same wet-chemical synthesis technique were studied and compared. The results indicate that in NP Eu3+ occupied only one site, A, while in NW Eu3+ occupied the same site, A and an additional site B due to crystal anisotropy. Furthermore, the electronic transition rate of D-5(1)-Sigma(J) F-7(J) in the NW increased from 14.9 to 28.9 ms(-1) compared to the NP, while the nonradiative transition rate of D-5(1)-D-5(0) decreased from 24.1 to 19.7 ms(-1). The luminescent quantum efficiency thus improved from 30% to 59%. This work demonstrates that a one-dimensional NW may be a more favorable device than a zero-dimensional NP for photoluminescence.
