Several factors can influence the absorption peak of nanomaterials:
Particle Size: The size of the nanoparticles can significantly alter the absorption peak due to quantum size effects. Shape and Morphology: Different shapes such as rods, spheres, and cubes can have different absorption characteristics. Surface Chemistry: The functionalization of the nanoparticle surface can shift the absorption peak. Material Composition: The elemental makeup and crystalline structure of the nanomaterial can also influence the peak.
