Optical Properties Characterization

The characterization of the optical properties of nanoparticles is a crucial aspect of nanotechnology, particularly due to their unique interactions with light that differ significantly from bulk materials. The ability of nanoparticles to interact with light at the nanoscale can significantly influence their performance in a range of applications, including drug delivery, photovoltaics, sensors, and catalysis. Nanoparticles exhibit size-dependent optical behaviors. Techniques that characterize these properties can unveil vital information about the size, shape, composition, and surface functionality of nanoparticles, ultimately guiding their integration into innovative technologies. Understanding these optical properties allows researchers to tailor the characteristics of nanoparticles for specific applications and improve their efficacy.

Nanoparticle Optical Properties Characterization Techniques

STEMart’s optical properties characterization service employs cutting-edge detection methods to provide thorough insights into the optical characteristics of nanoparticles.

• UV-Vis-NIR

UV-Vis-NIR spectroscopy can be used to analyze the absorption and transmission of nanoparticles in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. This method is particularly advantageous for assessing size-dependent behaviors and plasmonic properties of metallic nanoparticles.

• Photoluminescence (PL) Spectroscopy

PL spectroscopy detects the light emitted by nanoparticles when they are excited by photon absorption. This technique is especially effective for semiconducting and luminescent nanoparticles, revealing important details about their electronic structure and bandgap energies.

STEMART provides comprehensive optical properties characterization for a wide range of nanoparticle samples, including but not limited to:

• Surface Plasmon Resonance (SPR)
• Quantum Size Effects
• Photoluminescence
