“…However, when the Yb 3? doping concentration reaches 40%, the green and red luminescence intensities decrease, which are caused by the appearance of clustering and the concentration quenching effect at high RE concentrations [29]. In this case, the possibility of cross-relaxation (CR) between Yb 3?…”

In this paper, Ho 3? /Yb 3? co-doped Sodium Gadolinium Fluoride (NaGdF 4 ) phosphors were synthesized by a facile and efficient hydrothermal method. The samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), energy spectrum (EDS), and photoluminescence (PL). The results of XRD and SEM indicated that the prepared NaGdF 4 samples have the hexagonal structure and good orientation in the case of changing the concentration of Yb 3? . The results of pump power dependence of up-conversion intensity indicated that the energy transfer mechanism from Yb 3? to Ho 3? is a two-photon process. The energy transfer between Ho 3? and Yb 3? under 448 nm excitation was determined by PL spectra and fluorescence lifetimes. All the results proved that the doping of Yb 3? ions can effectively improve the upconversion luminescence of NaGdF 4 phosphors and achieve quantum cutting efficiency of up to 179.8%. Overall, NaGdF 4 :Ho 3? /Yb 3? have potential application in the field of optoelectronic materials.

“…The phosphor material should have good absorption and emission properties, good thermal and chemical stability, minimal thermal quenching and high quantum yield. This material should also be preferably inexpensive and easy to fabricate [1][2][3][4]. Trivalent RE 3 þ ions having 4f-4f inner-shell transitions possess specific advantage features such as high luminescence yield, narrow emission line, and long decay time constant.…”
