Abstract: A method for preparing a porous nano-fiber heterostructure photocatalytic filter screen includes: preparing a noble metal nanostructure with tunable spectra and a heterostructure composite photocatalyst of a photocatalytic material; and preparing a large area and multilayer porous nano-fiber filter screen structure, while utilizing a scattering enhancement effect of metal nanoparticles in an porous optical fiber to realize repeated conduction of sunlight in the optical fiber and finally interact with the composite photocatalyst on a surface to improve photocatalytic efficiency.

Abstract: The present invention provides a surface plasmon-optical-electrical hybrid conduction nano heterostructure and a preparation method therefor. The structure includes an exciting light source, a semiconductor nano-structure array, a two-dimensional plasmonic micro-nano structure, a sub-wavelength plasmon polariton guided wave, an emergent optical wave, a one-dimensional plasmonic micro-nano structure, a wire, a metal electrode, a conductive substrate, a probe molecule, an atomic-force microscopic conductive probe and a voltage source. The method achieves a semiconductor seed crystal with controllable distribution and density by controlling free metal ions, air, water or oxygen on a metal substrate to achieve highly uniform control of the seed crystal, and then strictly controls a length-to-diameter ratio and distribution of a semiconductor structure by continuous growth. Therefore, a new nano optics platform is provided for studying various novel effects produced by interaction between light and substances.

Abstract: A surface plasmon-semiconductor heterojunction resonant optoelectronic device and a preparation method thereof are provided. A surface ligand molecule is modified on a plasmonic nanostructure, a plasmonic crystal face structure is bound to the surface ligand molecule, a semiconductor nanostructure seed crystal is located on the plasmonic crystal face structure, a one-dimensional semiconductor nanostructure is located on the semiconductor nanostructure seed crystal, and all parts are in tight contact. The heterogeneous integration material achieves a lattice match at an interface, greatly reduces a loss caused by defects and rough crystal faces, and can achieve direct coupling of a surface plasmon mode and an optical mode. The heterogeneous integration material has a large application prospect in the fields of a nanolaser, a nano heat source and photoelectric detection and photocatalysis.
