Optical Properties of Sol-Gel Deposited Barium Strontium Titanate (BaxSr1-xTiO3) Films

Abstract

Optical properties of sol-gel deposited Barium Strontium Titanate (BaxSr1-xTiO3C for 1 h. Lattice parameters and grain sizes were determined for all the compositions. The band gap and refractive index values of the samples were determined from the optical transmission spectra for different compositions. Band gap of all the compositions were in the semiconductor range that would allow them to be used for photodiode and light sensor applications. Refractive index is reported for all the compositions.°, BST) thin films were studied to determine their suitability as light sensors. Crystallized BST films were formed by annealing in air at 700.
