Summary

Functional nanomaterials are advanced nanotechnology materials with potential features at nanoscale. Also, it can be defined as a compound that well controlled and organized by the molecular body, which is available in nanometer-level scale. It has been post-processed by chemically and physically to create specific properties like absorbance, fluorescence, strength, ductility, solubility, and wettability, which raw material did not subsist. Due to their extreme nanosize, they can be widely used in medicinal fields to penetrate biological systems in drug delivery and cancer treatment applications. Functional nanomaterials play vital role in fabrication of optoelectronic devices in semiconductor industries. Because of its magnificent physical, chemical, electronic, and optical properties, the functional nanomaterials can be potentially used in various technological applications that include solar cells, batteries, catalysis, drug delivery, and waste water treatment. In this chapter, we will discuss about chalcogenides and perovskite functional nanomaterials and their application toward fabrication of modern optoelectronic devices will be discussed in detail.
