abstract = "β-NaYF4:Eu3+microparticles co-doped with Gd3+ions were obtained by hydrothermal synthesis at 180 °C using citric acid as a stabilizing agent. All synthesized materials have a β-NaYF4crystalline phase, where the unit cell volume increases upon the addition of Eu3+and Gd3+ions. The particles have a hexagonal prism shape and a size of 40-714 nm, where Eu3+and Gd3+doping results in size reduction. Upon 393 nm excitation, phosphors exhibit distinct emission peaks centered at 591, 615, and 695 nm and a weak band at 650 nm attributed to5D0-7FJtransitions (J= 1-4). The optimum Eu3+doping concentration was found to be 30% in the NaYF4host. Concentration quenching was realized through dipole-dipole interactions. Kinetic measurements showed a gradual decline of the5D0lifetime from 6.7 ms to 2.2 ms along with an increase in Eu3+doping concentration. Co-doping of the small Gd3+number led to an increase of emission intensity and5D0lifetime. The effects of Eu3+doping and Gd3+co-doping on radiative and nonradiative decay rates were studied using 4f-4f intensity theory.",
