Facile Synthesis of Highly Water‐Soluble Lanthanide‐Doped t‐LaVO₄ NPs for Antifake Ink and Latent Fingermark Detection

In the information age, it is important to protect the security and integrity of the information. As a result, the fluorescent ink as an antifake technology and the fingermark as an information carrier have aroused great interest. In this work, highly water-soluble lanthanide (Ln3+ )-doped tetragonal phase (t-) LaVO4 nanoparticles (NPs) are successfully obtained via a simple, fast, and green microwave-assisted hydrothermal method. The average...
