Nanostructured thin films of metal oxides/ chalcogenides with various morphologies viz., particles, wires, rods, tubes, plates etc., have been significantly envisaged in various optoelectronic devices including thin film transistors, photoelectrochemical cells, heterojection-based solid-state solar cells, polymer solar cells, gas sensors, dye-sensitized solar cells, batteries and supercapacitors etc. I am actively involved in synthesis of these nanostructures using various solution-processes for designing various devices. To suffice requirements of device, novel structures have been synthesized and successfully evaluated. Since single component metal oxide/form cannot satisfy all essential requisites for a specific optoelectronic device, so emphasis has been made to synthesize property oriented nanostructures to provide a much-needed functionality. For example, when one wish to use metal chalcogenide/oxide as counter electrode like platinum, then synthesized nanostructures of NiS, CoS, FeO3 etc., should necessarily possess catalytic properties.
In this presentation, the benefits of solution-processed metal oxide/ chalcogenides nanostructures in the areas of energy (conversion and storage), chemical sensors along with synthesis approach will be discussed. Moreover, biological applications including protective antigen detection and antibiotics in addition to gas sensors and supercapacitors will be highlighted. Attempts will be made to strengthen the application potentiality of acquired skills for in-depth understanding through discussions followed by suggestions.
