Photochromic effect of HoPO₄:Li⁺ powder

【摘要】 Lit-doped Ho PO4 powders with a pure tetragonal phase are successfully synthesized by the co-precipitation method. It exhibits an obvious color change under sunlight and tri-phosphor fluorescent light illumination.The introduction of Litions into Ho PO4 can further enhance its photochromic property effectively. The doped Litions induce changes in the crystal structure. The spectral characteristics and thus photochromic properties of Ho PO4 are explored. The improved Ho PO4 powder, when used as a photochromic material, has wide-ranging prospects in security, decoration, and other applications.更多还原
