Precursor Based Tuning of the Nonlinear Optical Properties of Au-Ag Bimetallic Nanoparticles Doped in Oxy-fluoroborate Glasses
Source abstract
Abstract
Abstract This work brings out the importance of precursors (AgNO3, AgCl, and AgI) that involve in tailoring the optical properties for the Au-Ag bimetallic nanoparticles doped in the dichroic glasses. The incorporation of silver nanoparticles in 20Li2O-15CaF2-20ZnO-45B2O3 matrix along with gold has reduced the average size of nanoparticle and has enhanced the nonlinear refractive index. The absorption spectra hints that there could be the possibility of surface plasmon resonance (SPR) overlap of Ag and Au as there is no prominent peak of Ag nanoparticles in the blue region. It is found that the sample doped with Au-AgNO3 has lesser bandgap energy compared to Au-AgCl and Au-AgI respectively which had thereby increased more NBO's in the matrix which in turn results in better nonlinear optical properties for Au-Ag NO3.
