Abstract:- In this work the silicon dioxide powder was prepared by optimized and simple sol-gel
method and also provides a basic understanding of the effect of surfactants on the growth of
SiO2. The precursor solutions were made by mixing tetraethylorthosilicate (TEOS) with
surfactants dimethyl-formamide or formamide and isopropanol and deionized water. The silica
powder calcinated at 500oC formed in this study was found to be spherical structure. We deal
with different surfactants, which are helpful for the enhancement of optical properties and
surface morphologies. Optical properties of the samples were characterized by PL spectroscopy
and growth rate of SiO2 can be observed through scanning electron microscopy. SEM and PL
analysis revealed that all the required morphologies and excitation and emission intensity were
observed which were indicative of the successful synthesis of silica particles.
