Abstract Influence of temperature on the photoluminescence of rhodamine 6G deposited on 2D array of the gold nanoparticles was studied in the temperature range 78–278 K. The factor of surface plasmonic enhancement of rhodamine luminescence was found to decrease monotonically with increasing temperature. Electron-phonon scattering and thermal expansion of the gold nanoparticles were considered as two competing physical mechanisms of the temperature dependence of plasmonic enhancement factor. The calculations showed the significant prevalence of the electron-phonon scattering that causes the temperature induced decrease of plasmonic enhancement of rhodamine 6G luminescence observed.
