Abstract: | Nanostructured coatings have recently attracted increasing interest because of the possibilities of synthesizing materials
with unique physical-chemical properties. Highly sophisticated surface related properties, such as optical, magnetic, electronic,
catalytic, mechanical, chemical and tribological properties can be obtained by advanced nanostructured coatings, making them
attractive for various industrial applications. In this report we describe our efforts at developing methodology for the fabrication
of SrFeO3-x based thin films using a modified Pechini method. Thin films of SrFeO3-x were fabricated using spin coating and a drop coating method developed in-house on Al2O3 and Si- substrates. The films annealed at 600°C for one hour show a perovskite phase. The grain size increases with increase
in annealing temperature. The influence of various variables such as metal to chelant ratio, drying control reagents, calcination
conditions, substrate type and mode of film formation were studied using XRD, optical microscopy, SEM and AFM. |
