Enhanced adsorption and non-linear optical properties of DNA-CTAB functionalized mesoporous silica nanoparticles and their influence on enhancement of photoluminescence of Rhodamine 6G dye

We report a novel template method for synthesizing silica nanoparticles that are mesoporous as well biocompatible. The were synthesized using the Stober process and peptization method. have used surface-modified deoxyribonucleic acid (DNA) with cetyl trimethyl ammonium bromide capping agent. obtained particles analyzed x-ray diffraction, UV–vis spectroscopy, Brunauer–Emmet–Teller method, scanning electron microscopy, open aperture Z-scan technique. characterization results indicated DNA polymer’s presence influenced formation of particles. mesoporous, nanosized, good adsorbent also show enhanced non-linear optical properties when compared existing nanoparticles. solubility was verified in dimethyl sulfoxide (DMSO). surface area reduced porous size photoluminescence Rhodamine 6G dye DMSO. This can be applied to lower lasing threshold gain medium applications. Hence, variety applications such they adsorbents nanosized particles, which is applicable drug delivery purposes, bioimaging, catalytic activities, doping thin film making, biosensing applications, improvement material quality solar devices. property limiting photonic
