摘要：
As a new nanomaterial, HgWO4 nano films 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 nano films' PL intensities and TiO2 doped amounts are in good agreement with Gaussion function, and maximum PL intensities of HgWO4 nano films are located at 3.8% ratio of TiO2 nanoparticles.
