Abstract
Nanomaterials (NMs) particularly synthesized by green routes have attracted researchers
and scientists for their multifunctional industrial applications. NMs have not only revolutionized research,
but also our daily life because of numerous applications in medical diagnostics, consumer
products, and energy-related applications. Their unique properties are directly related to chemical
composition, structure, size and shape. There are several characterization techniques used to determine
the size, composition, crystalline structure and other physical properties of NMs. Prominent among
them are spectroscopic techniques such as UV-Visible, FTIR, EDX; diffraction techniques such as
XRD, SAED; microscopic techniques such as SEM, TEM, AFM and others such as Zeta potential
measurements. Every technique has its own merit and demerit. This mini review describes the uses of
UV-Vis spectroscopy in characterization of NMs.
Keywords:
Nanomaterials, UV-Vis spectroscopy, localised surface plasmon resonance, beer-lambert law, characterization techniques, AFM.
