What Factors Influence Photoluminescence in Nanomaterials?
Several factors can influence the photoluminescent properties of nanomaterials:
Size and Shape: The size and shape of nanoparticles can significantly affect their emission wavelength and intensity due to quantum confinement effects. Surface Chemistry: The surface states and functional groups on the nanoparticles can trap or recombine charge carriers, affecting the photoluminescence efficiency. Material Composition: The elemental composition and crystalline structure of the material play a crucial role in determining its photoluminescent properties. Environmental Factors: The presence of solvents, pH levels, and other environmental factors can influence the photoluminescence behavior of nanomaterials.
