Abstract

The demands for highly transparent thin films for many integrated optical systems increase rapidly. The aim of the present work is to address these important needs. We show a novel approach for the nanocolloidal processing of barium titanate with enhanced optical transparency. The results showed that the stability of the prepared solution and optical transparency of the resulted thin film improved significantly. The study of the structure and properties of the prepared solutions indicated that the enhanced and homogenous transparency is due to the size-effect of the particles embedded in the solution, which are nanostructured. It seems to us that the proposed method has the capability of being a general strategy for obtaining highly transparent solutions and thin films. Moreover, the enhanced transparency of the prepared thin films can improve the energy efficiency of the solar power systems significantly.
