Single nanocrystal spectroscopy is employed to demonstrate metal-enhanced optical response of Er<sup>3+</sup>/Yb<sup>3+</sup> doped up-conversion nanocrystals deposited on graphene upon coupling with silver nanowires. Direct interaction between nanocrystals and graphene results in quenching of up-conversion emission and shortening of luminescence decay times, due to the energy transfer to graphene. The amount of the energy absorbed by graphene can be enhanced by coupling Er<sup>3+</sup>/Yb<sup>3 ...[more]
