Luminescent Sol-Gel Coatings Based on Nanophosphors

摘要

Nanoparticles of lanthanide vanadate (YVO{sub}4:Ln) and phosphate (LaPO{sub}4:Ln) are obtained by simple aqueous syntheses. The nanoparticles obtained are stabilized in colloidal suspensions and deposited in sol-gel films by spin-coating using a silicate as inorganic binder. The influence of the thermal treatment on the brightness and the ability to achieve multilayer coatings are discussed.
