摘要: The invention relates to a preparation method and application of an Fe3O4/SiO2@Gd2O3:Eu,Bi magnetic-fluorescent nano material. CTAB (cetyltrimethylammonium bromide) modified Fe3O4/SiO2 composite nanoparticles are used as the core, gadolinium, europium bismuth rare-earth fluorescent material is shell obtain simple easy implement, prepared has stable properties store. Besides, can act on fingerprint residues, clearly develop fingerprints under ultraviolet lamp; advantages low consumption high sensitivity, be for photographic recording, greatly enhance success rate development (especially searching within wide range), therefore, applied methods developing skin, glass, ceramic, wall surface other substrates.
