▎ 摘　　要

Graphene oxide (GO) was prepared using the improved Hummer method, and mono-dispersed manganese cobalt nickel oxide (MCN) semiconductor nanometer particles were synthesized and coated with GO. Under 980-nm infrared laser excitation, this novel hybrid material demonstrated nanometer-scale surface plasmon resonance. The same mechanism has previously only been reported in good conductors. Although the MCN semiconductor is a negative temperature coefficient material, it can realize the same effect as a good conductor. The experimental data indicated that the hybrid material absorbed infrared laser photothermal energy with a transformation efficiency more than fourfold larger than that of pure mono-disperse MCN semiconductor nanopowder. The chain heat conductivity velocity of the hybrid material compares favorably with that of metal in that it alters the laser radiation energy heat transfer method on the surface. The hybrid material is one new kind of photothermal energy transfer material by new chain nanoscale surface plasmon mechanical, it can absorb sunlight and ultra-red light totally, and is one excellent energy transform and absorb material for sunlight.
