Inductively coupled plasma (ICP) is a type of plasma source created by transferring energy from an oscillating electric field to a gas, typically argon, resulting in the ionization of the gas and the generation of a high-temperature plasma. This technology is widely used for its ability to produce uniform and stable plasmas, making it ideal for various applications, especially in the synthesis of nanomaterials. ICP plays a crucial role in enhancing the properties of nanomaterials by enabling precise control over their size, shape, and composition during synthesis.
