摘要: Photoluminescence enhancement of CdSe/CdS/ZnS QDs by localized surface plasmon resonance large Au-NPs has been investigated. The photoluminescence the with an emission wavelength at 620 nm in a PMMA matrix is enhanced immobilized Au-NPs. By considering lifetime and excitation dependent we realized that rate enhancements both contributed to total enhancement. PL measurements were carried out for different sizes find their influences on QDs. The largest is achieved applying 80 Silanization method gives us opportunity easily to prepare samples concentrations It revealed that increasing concentration Au-NPs layer provides higher scattering cross section which contributes PL
