Abstract

As a new nanomaterial, HgWO₄ nanofilms are prepared by the self-inventive technique of collodion nanoparticles-dispersal and film-formation. Their photoluminescent properties are enhanced and then controlled through nano-TiO₂ doping. These approaches not only ensure film uniformity and fluorescence (FL) enhancement, but also realize a FL increase/decrease conversion effect. The relationships between HgWO₄ nanofilms' PL intensities and TiO₂ doped amounts are in good agreement with Gaussion function, and maximum PL intensities of HgWO₄ nanofilms are located at 3.8% ratio of TiO₂ nanoparticles.
