• Atomic force microscopy (AFM) was used to analyze surface morphology and grain size distribution.
• X-ray diffraction (XRD) analysis was performed to identify crystallographic phases.
• Energy-dispersive X-ray analysis (EDX) was utilized to assess material composition and its dependence on process parameters.

Main Results:

• Optical properties were found to be dependent on the process parameters and resulting film composition.
• Surface morphology, crystallographic phases, and grain size distributions varied with processing conditions.
• Energy-dispersive X-ray analysis confirmed a direct correlation between optical constants and process-dependent compositions.
• Optimized process parameters enabled the formation of amorphous films.

Conclusions:

• The optical and structural properties of MgO-Al2O3-ZrO2 ternary mixed-composite films are significantly influenced by process parameters.
• A strong correlation exists between film composition, processing conditions, and optical constants.
• Environmentally stable amorphous films with high packing density can be achieved through optimized processing conditions.
