Upconversion luminescence (UPL) characteristics and effects of Li+ ion on the UPL of ZnWO4:Yb,Er polycrystalline phosphors were investigated. It was shown that introduction of Li+ ions could reduce the calcination temperature by about 200 °C and increase the crystallinity of ZnWO4:Yb,Er by a liquid-phase sintering process via formation of Li2WO4 and other intermediates. UPL efficiency is remarkably promoted by Li+ ions. Moreover, the UPL spectrum of Li+-doped ZnWO4:Yb,Er presents a red shift, and the strongest peak position shifts from 553 to 559 nm. These can be attributed to a shift in the 4f level barycenter to lower energy, which results from lowering of the symmetry of the crystal field around Er3+.

Synthesis process and luminescence properties of trivalent lanthanide ions (Ln3+) doped YF3 nanoparticles have been investigated. To synthesis Ln3+-doped YF3 nanoparticles, the mixture of (YCl3·nH2O + LnCl3·nH2O), and NH4F was hydrothermal treated at 180 °C in a Teflon-liner auto-clave or heated at higher temperatures (400 °C ∼ 600 °C) in a stove. The XRD patterns showed that the Ln3+-doped orthorhombic YF3 nanoparticles with no second phase have been prepared. The solid solution Y1−xEuxF3 (x = 0 ∼ 0.4) nanoparticles have been synthesized. The luminescence concentration quenching resulted from resonance energy transfer between neighboring Eu3+ ions occurred at higher Eu3+ concentrations (30 mol%). The upconversion luminescence of Er3+−Yb3+ codoped YF3 nanoparticles under 980 nm excitation has also been observed. With increase of heated temperature, the size of the Er3+−Yb3+ codoped YF3 nanoparticles increased gradually, and upconversion luminescence intensity increased significantly.
