In this paper we describe the optical and fluorescence features of metal nanoparticles by analytical model based on fundamental quantum mechanical principles. Here, we examine the plasmonic property of gold nanospheres with radii range from 10 to 1 (extending from classical to quantum regime). Electrical permittivity and fluorescence emission of nanoparticles with ranging size below 10 nm have significant difference with classical nanoparticles. Considering quantum mechanical effects, the results indicate clear blue shift and weakening of fluorescence peaks of gold nanospheres.
