    The present manuscript researches the near infrared quantum cutting luminescence phenomena of Yb3+ ion in YVO4 crystal matrix. The luminescence spectra, excitation spectra and fluorescence lifetimes were measured. It was found that the excitation of YVO4 crystal matrix energy band by 322.0 nm light can result in the effective secondary cooperative energy transfer of Yb3+ ion from the YVO4 crystal matrix. It results in the intense 985.5 nm 2F5/2→2F7/2 near infrared quantum cutting luminescence of Yb3+ ion. Meanwhile, the 430.0 nm luminescence intensity of YVO4 crystal matrix decreases greatly. From the experimental measurements, it was found that the lifetime of 430.0 nm fluorescence of (A) Yb(1.5)∶YVO4 crystal is τA=3.785 s and that of (B) YVO4 crystal is τB=22.72 s. It was found also that the theoretical efficiency up limit of quantum cutting of (A) Yb(1.5)∶YVO4 crystal is aboutη1.5%Yb=183.3%.
