Abstract

In this study, the influence of the concentrations of ytterbium and thulium ions on the dependence of the luminescence intensity of NaYF \({}_{4}\) :Yb/Tm nanoparticles on the mode and intensity of optical pumping is considered. Two modes of luminescence excitation are analyzed: continuous and pulsed. It has been established that variation in the concentrations of ytterbium and thulium does not lead to a change in the shape of the curve describing the dependence of the luminescence intensity of the nanoparticles on the intensity of optical pumping under both pulsed and continuous excitation.
