TL;DR: The luminescence intensity is improved significantly after core-shell formation due to extent of decrease of non-radiative rates arising from surface dangling bonds and capping agent and to improve crystallinity.

TL;DR: The effect of Li+ co-doping on the photoluminescence properties of YPO4:Eu is discussed in this article, where interesting properties such as the presence of intermediate bands, shifting of the Eu-O CTB to a lower wavelength, variation in intensities of magnetic and electric dipole transitions of Eu3+ and shift of 5D0 → 7F0 to higher energy with increasing excitation wavelengths are observed.

TL;DR: The luminescence intensities and lifetimes increase significantly with increasing heat-treatment temperature of the doped samples, and this is attributed to the reduction of H(2)O from the surface of the particles and a non-radiative process after heat treatment.

TL;DR: The high resolution TEM suggests a change in orientation of the crystal on annealing up to 900 °C as well as the solubility limit of Eu(3+) ions at the Ca(2+) sites is up to 3 at.

TL;DR: In this paper, the tuning of blue to pink color generation from Li+ ion co-doped YPO4:5Eu nanoparticles prepared by polyol method at ∼100-120 °C with ethylene glycol (EG) as a capping agent was explored.
