Abstract: Rare earth ion doped GdVO4 phosphors have been used in laser, luminaire, luminescent display and other fields, but there are few reports for latent fingerprint. In this paper, a series of Bi3+ and Re3+ (Re = Eu, Dy, Tm) singly doped GdVO4 and Bi3+ and Re3+ double doped GdVO4 phosphors were synthesized by high temperature solid method. The structure and characteristics of luminescence were described by X-ray powder diffraction and photoluminescence spectrum. We tried to apply prepared phosphors to the latent fingerprint detection field, and found that GdVO4: Bi3+, Eu3+ phosphor has lower background interference, and can effectively display latent fingerprint details under different surfaces, wet environments and high temperature conditions. The Bi3+, Eu3+ co-doped GdVO4 phosphor is a promising phosphor material for latent fingerprint identification application.
