【 摘 要 】

ZrO₂:Yb³⁺-Ho³⁺ phosphors with different Yb³⁺ doping concentration have been prepared by coprecipitation method. X-ray diffraction (XRD), scanning electron microscope (SEM) and photoluminescence spectra were used to characterize the properties of ZrO₂:Yb³⁺-Ho³⁺ phosphors. Different phases of ZrO₂ can be obtained by changing the concentration of Yb³⁺. Under the 980 nm excitation, the sample gives a set of light: strong green (539 nm), weak red (670 nm) and near-infrared (760 nm). The upconversion luminescence is based on two-photon absorption by the energy transfer from the donor (Yb³⁺) to the acceptor (Ho³⁺). All the results indicate that ZrO₂:Yb³⁺-Ho³⁺ phosphors could be a promising biological labelling material.
