Quantum Dots (QDs) are quasi-zero-dimensional semiconductor quantum structures [1] which are used in photovoltaics and optoelectronics. In the luminescent materials QDs are a source of excitons which interact with plasmon (derived from metal nanoparticles) and create the hybridized plasmon-exciton [2] mixed states, called plexcitons [3]. Here, we present novel nanoplasmonic composites obtained by nonchemical method - NanoParticle Direct Doping (NPDD) [4]. Nanocomposites are made from Na5B2P3O13 (NBP) glass matrix doped with silver nanoparticles (nAg) and optically active cadmium telluride quantum dots (QDCdTe). The obtained materials will be presented and their electromagnetic properties, characterized by transmission, reflection and photoluminescence measurements in UV/VIS and IR regions. We will also present the potential areas of application of the fabricated materials, such as QDs based laser [5].
