Pengaruh Komposisi Dan Suhu Annealing Terhadap Energi Gap Film Tipis Barium Zirkonium Titanat

---

Thin films of Barium Zirconium Titanate (BZT) with the composition BaZr0,8Ti0,2O3,
BaZr0,75Ti0,25O3, and BaZr0,7Ti0,3O3 were prepared using the sol-gel method prepared
by spin coating at a speed of 3000 rpm for 30 seconds. The annealing temperature of
each composition was 600oC and 650oC, which were annealed for 1 hour. Thin films
were characterized using ultraviolet-visible spectroscopy to determine the absorbance
value. From the absorbance value, the value of transmittance, refractive index,
thickness, absorption coefficient and energy bandgap is obtained. The energy
bandgap values of the BaZr0,8Ti0,2O3 thin film at 600oC and 650oC are 3.62 and 3.70
eV, respectively, for BaZr0,75Ti0,25O3 thin films are 3.70 and 3.79 eV, and for films
thin BaZr0,7Ti0,3O3 is 3.81 and 3.69 eV. The results obtained from the energy bandgap
width (Eg) show that the energy bandgap value decreases with increasing annealing
temperature and the energy bandgap value fluctuates as the composition increases.
Keywords: thin layer, sol-gel method, composition, temperature, energy bandgap
