Pengaruh Suhu Annealing terhadap Struktur Mikro dan Sifat Optik Lapisan Bismuth Ferrite (BiFeO3)

Abstract

This study aims to determine the effect of annealing temperature on the microstructure and optical properties of Bismuth Ferrite (BiFeO3) layers. BiFeO3 film was successfully deposited on a quartz substrate using the Chemical Solution Deposition (CSD) method. The microstructure was characterized by XRD and optical properties was characterized with UV-Vis spectrophotometer. The annealing temperature variations are 550 o C, 600 o C, and 650 o C. Annealing temperature affect the microstructure i.e., crystallite size, crystallinity, lattice parameters and optical properties i.e., absorbance and energy gap. The crystallite size, crystallinity, and lattice parameters increase with increased annealing temperature. The peak of absorbance has decreased with the increase in annealing temperature. The lowest energy gap is at 650 o C annealing temperature which is (2,45 ± 0,02) eV.

Microstructure and Optical Properties Study of Nd-doped BiFeO3 (Ba1-xNdxFeO3) Films on Quartz Substrate

“…Moreover, there have been many studies that reported the Nd-doped BFO films deposited on (111) Pt/Ti/SiO2/Si [10], and transparent FTO [8,11], ITO [13], SRO [3], LAO [17] substrates. Also, among the available methods, thin film manufactured by a chemical solution deposition (CSD) or solgel method [18][19][20][21] has potential advantages, which are easy operation, low cost, high purity, and low heating temperature. However, few works have concerned Nd-doped BFO thin films with various doping levels depositing on transparent quartz substrates.…”
