The enhancement of photoluminescence of Au-TiO₂ nanoparticles by surface plasmon resonance has been studied extensively by experiment in recent years. For the purpose of optimizing the photoluminescence property of Au-TiO₂ nanoparticles, the manufacturing parameters related to the Au nanoparticles and TiO₂ nanoparticles need to be considered. In this paper, Drude model and Maier"s effective volume method are used to analyze the variation of the metal nanoparticle radius, separation between metal nanoparticle and dielectric molecule, and total absorption cross-section with original radiative efficiency on the photoluminescence property of Au-TiO₂ nanoparticles. The results show that to obtain the optimized enhancement factor for photoluminescence process, the size of Au nanoparticle is about 13 − 20 nm , the separation between Au nanoparticle and TiO2 molecule is about 5 −15 nm , the total absorption cross-section of TiO₂ molecules is about 1−100 nm2 and the original radiative efficiency of TiO₂ molecule is weak about 0.001− 0.1 . With these fabrication parameters, the photoluminescence property of Au-TiO₂ nanoparticles can be enhanced several thousand times compared to traditional TiO₂ nanoparticles.
