Overview

Ultraviolet–visible-near infrared (UV–Vis-NIR) spectroscopy is a powerful, rapid, and non-destructive technique for investigating the optical properties of nanomaterials. Because nanoscale structures interact strongly with light, their UV–Vis-NIR spectra provide valuable information about electronic transitions, band-gap energies, particle size, aggregation, and surface plasmon resonance.

This presentation introduces the fundamental principles of UV–Vis-NIR spectroscopy and highlights its applications in the synthesis and characterization of metallic and composite nanomaterials. Particular attention is given to monitoring nanoparticle formation, evaluating colloidal stability, estimating optical band gaps, and examining changes caused by surface modification or interactions with chemical species.

Key Learning Objectives:

Learn how UV-Vis-NIR spectroscopy enables rapid, non-destructive characterization of nanomaterials.
Apply UV-Vis-NIR spectroscopic techniques to monitor nanoparticle synthesis, evaluate colloidal stability, and characterize key nanomaterial properties such as particle size, aggregation, and surface plasmon resonance.
Interpret UV-Vis-NIR spectral data to estimate optical band gaps and assess the effects of surface modifications and chemical interactions on metallic and composite nanomaterials.

Who Should Attend:

Nanomaterials researchers and scientists working on metallic nanoparticles, quantum dots, nanocomposites, and advanced functional materials.
Materials scientists and engineers involved in the synthesis, characterization, and optimization of novel materials.
Academic researchers and postdoctoral fellows studying optical, electronic, or photonic properties of nanostructured materials.
Graduate and postgraduate students in materials science, chemistry, nanotechnology, physics, and chemical engineering.
