Zinc germanate (Zn 2 GeO 4 ) is a typical n-type semiconductor with numerous advantages that make it an excellent matrix for luminescent materials. The transition metal manganese (Mn) has multiple oxidation states, which makes it an excellent luminescent ion center. Here we present a facile low-temperature and short-time preparation of Zn 2 GeO 4 :Mn 2+ (ZGOM) nanoparticles. The method is capable of synthesizing short rod-shaped luminescent nanoparticles with regular shape, uniform size, and ideal luminescence performance within 1 h at a temperature of 220 °C. The phase structure and microstructure of ZGOM were characterized by XRD, XPS, and SEM, and its fourier transform infrared (FT-IR), ultraviolet absorption (UV–vis), and photoluminescence (PL) spectra were collected and analyzed to further characterize the luminescence properties of the products. In addition, the growth mechanism and luminescence mechanism of the ZGOM were discussed in detail, and exploring the application prospects in the latent fingerprint information manifestation.
