Microwave-assisted synthesis and photothermal conversion of Cu2-xSe hollow structure

摘要

The Cu2-xSe nanostructure is rapidly synthesized via one-pot microwave-assisted method. Excellent aqueous dispersion Cu2-xSe hollow structures with an average diameter 160-180nm and a shell thickness 11.3nm are obtained successfully. The formation mechanism of the hollow structure is discussed in detail. The NPs exhibits a superior photostability and photothermal conversion efficiency (48) owing to its unique cavity effect and LSPR property.
