摘要：

Gold nanoparticles can generate near field due to surface plasmon resonance (SPR) in the visible region. Such near field has the ability to enhance fluorescence of optimally proximal emitters. We have observed augmented green (intrinsic) and red (Eu3+) emission under UV excitation (375 nm) from an important semiconductor ZnO:Al, Eu3+ when optimally conjugated with gold nanospheres. Local field generated by gold nanosphere (similar to 30 nm) is simulated through finite difference time domain method, and a direct correlation with fluorescence enhancement is established.
