Lasing Capability Enhancement by Metallic Nanoparticles: A Short Review

Abstract

he exploration of science and technology deal with the manipulation of the physical properties at the atomic scales has driven a new interest in coupling of metal nanoparticles in rare earth doped inorganic glasses. The coupling of nanoparticles into the rare earth doped glass brings significant enhancement in the luminescence intensity. This enhancement is expectedly due to the 'plasmonic wave’ (referring to the coherent coupling of photons to free electron oscillations called plasmon) occurs at the interface between a conductor and a dielectric. Besides that, the efficient energy transfer between the excited rare earth ion and metal nanoparticles that act as a transmitter and receiver increased the radiative emission rate and reduced the non -radiative decay rates. This short review briefly discussed the phenomena of interaction of light with rare earth doped glasses embedded with metallic NPs and its significance influence on the performance of the lasing glass. On the other hands, the influence of magnetic nanoparticles in rare earth doped glass that possibly activate the luminescence quenching of lasing glass also will be elaborately discussed. Some significantly new findings are highlighted and facilely analyzed.
