“…Further, it is also evident that at any wavelength, the refractive index increases with the increase in annealing temperature. These observations are in accordance with the earlier reported results [5][6][7][8]. …”

Ceria-stabilized zirconia (CSZ) thin films have been developed over Ni-based alloy substrate by vacuum evaporation method using an electron beam. X-ray diffraction (XRD) analysis of the film heat treated at different temperatures reveals monoclinic phase stabilization. Transmission measurements of the films annealed at different temperatures, in the wavelength region 300-1,100 nm, indicate that the band gap energy of the films lies between 3.6 and 3.8 eV. Refractive index of the films was found to increase with the increase in the annealing temperature. Micro hardness of the films increases nonlinearly with the increase in annealing temperature, indicating an improvement in the hardness of the films. Thermal conductivity studies of the CSZ-coated substrate show a nonlinear decrease with the increase in annealing temperature. Surface investigations of the CSZ films confirm an increase in grain size and a decrease in surface roughness with the increase in annealing temperature of the films.

“…One of them is achieved by the synthesis of ZrO 2 adopting different solution-based techniques [15] for the development of chemically stabilized t-ZrO 2 below 1200°C. Herein, sol-gel route [19][20][21][22][23][24] is widely applied among these solutionbased techniques. This approach has significant advantages such as precise compositional [25][26][27] and microstructural control [28,29], excellent chemical homogeneity [28] and high purity product [26] after annealing.…”

“…The precursor for the sol was a mixture of isopropoxide Zr(IV) and isobutanole stabilized with 2,2 0 -diethanolamine, concentration n(DEA)/n(metal) = 1. The viscosity was enhanced by adding polyvinylpyrrolidone (PVP) with a concentration of n(PVP)/ n(metal) = 0.3max [12,13].…”
