Hybrid Graphene Oxide and NTC Semiconductor Material Absorbs and Transform Light Energy via a Novel Surface Nanoscale Plasmon Mechanical

摘要: Graphene oxide (GO) was prepared using the improved Hummer method, and mono-dispersed manganese cobalt nickel (MCN) semiconductor nanometer particles were synthesized 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 MCN is a negative temperature coefficient material, it can realize effect as conductor. experimental data indicated that absorbed photothermal energy transformation efficiency more than fourfold larger of pure mono-disperse nanopowder. chain heat conductivity velocity compares favorably metal alters radiation transfer method on surface. one new kind by nanoscale mechanical, absorb sunlight ultra-red light totally, excellent transform for sunlight.
