Note: LSPR energy is sensitive to the dielectric performance of the material and the surrounding environment of nano supercapacitors , shape and size of nanoparticles. That is, if a ligand such as a protein is attached to the surface of metal nanoparticles, its LSPR energy changes. Similarly, LSPR effects are sensitive to other changes in nanosupercapacitors, such as the spacing between nanoparticles, which can be altered by the presence of surfactants or ions.
One of the consequences of the LSPR effect in metal nanoparticles of nano supercapacitors is the ability to absorb visible waves due to the coherent oscillations of plasmons. In nano supercapacitors, colloids of metal nanoparticles such as silver or gold can produce colors such as red, purple or orange. show that cannot be seen in normal dimensions. This color change depends on the shape, size and surrounding environment of silver nanoparticles in nano supercapacitors . In the structure of nano supercapacitors, one of the nano properties that distinguish metal nanoparticles from these large-scale materials is their optical properties. This is due to the localized surface plasmon resonance. In simpler terms, when light hits metal surfaces of any size, some light waves travel along the metal surface. By creating surface plasmon, these waves actually give part of their energy to surface electrons and cause them to vibrate (scatter) . When plasmons are generated in bulk metals, electrons can move freely through the material without recording any traces. In nanoparticles, the surface plasmon is placed in a limited space, so that the electrons oscillate back and forth in this small space and in the same direction. This effect is called Localized Surface Plasmon Resonance (LSPR), when the frequency of these oscillations is the same as the frequency of the light causing the plasmon, it is said that the plasmon is in resonance with the light.
Light absorption also occurs in ordinary nano supercapacitor materials that have a continuous energy band, and electrons are transferred from the valence band to the conduction band, although here thermal energy can also cause electrons to be excited to the conduction band. Nanoparticles of nano supercapacitors also have discrete energy levels like atoms. Therefore, nanoparticles of nano supercapacitors are also called artificial atoms. Also, nanoparticles below 01 nm and especially semi-conducting nanoparticles in nano supercapacitors are called quantum dots. By changing the size of nanoparticles of nano supercapacitors , the distance between the energy levels in them changes. whatever size Nanoparticles become smaller, the distance between the energy levels and the forbidden band increases, and the larger the size of the particles, the distance between the energy levels decreases. This point makes it possible to adjust the distance between their energy levels by changing the size of nanoparticles in nano supercapacitors so that they absorb certain waves. For example, the dimensions of nanoparticles of a specific type in nano super capacitors can be adjusted so that they absorb infrared, ultraviolet, radio waves, etc. This feature is widely used in nano supercapacitors of military industries and nano supercapacitors of electronics.
Conclusion :
Note: LSPR energy is sensitive to the dielectric performance of the material and the surrounding environment of nano supercapacitors , shape and size of nanoparticles. That is, if a ligand such as a protein is attached to the surface of metal nanoparticles, its LSPR energy changes. Similarly, LSPR effects are sensitive to other changes in nanosupercapacitors, such as the spacing between nanoparticles, which can be altered by the presence of surfactants or ions.
