For the structure of the luminescent material (8-hydroxyquinolinato)aluminium (Alq₃) and Ag nanoparticles,surface plasmon resonance wavelength and amplification ability of Alq₃ luminescence localized by changes in particle diameter of Ag nanoparticles and changes in distance between Ag nanoparticles and luminescent substances were investigated. And observed the temperature dependence of the time-resolved PL spectroscopy, we clarified the dynamics of luminescence amplification by localized surface plasmon resonance of Ag nanoparticles from the change of radiative lifetime.
