Fluorescence from the Compound System of PVK Molecules and SiO₂ Nanoparticles with Different Sizes

Abstract:

SiO₂ nanoparticles (NPs) are synthesized in ethanol solution and mixed with polyvinyl carbazole (PVK). The sizes of SiO₂ NPs are 40nm and 60nm. PVK/SiO₂ NPs compound systems with different sizes and with different ratios of mass fraction are obtained. Photoluminescence spectra are employed to research the optical properties of PVK molecules and PVK/SiO₂ NPs compound system. In compound system, the process of interface energy transfer between PVK and SiO₂ NPs are observed. The mainly energy transfer form is nonradiative resonance transfer.
