Abstract
Metal enhanced luminescence using alloy nanoparticles offers additional degrees of freedom for tuning their optical properties by altering atomic composition and atomic arrangement when compared to pure metal nanoparticles such as gold and silver. Surface plasmon resonance wavelengths of silver-copper nanoparticles were tuned in the visible and near infrared region by changing annealing temperature. Strong emission enhancement of luminophores at the vicinity of the Ag—Cu nanoparticles was shown when the SPR spectrum was tuned to produce maximum spectral overlap. As the SPR spectrum can be easily tailored, this platform can be effectively used to enhance luminescence of different luminophores.
