ZnO nanowires dị ezigbo mkpa otu akụkụ nanomaterials.Ọ nwere ọtụtụ ngwa na mpaghara nanotechnology.Dị ka ultra-sensitive chemical biological nanosensors, dye solar cell, light-emitting diodes, nano lasers na na.
Njirimara ndị bụ isi nke ZnO nanowires.
1. Arụmọrụ ikuku ikuku
The warara na ogologo geometry nke nanowires na-egosi na ezigbo ubi emission ngwaọrụ nwere ike.
2. Ngwa anya
1) Photoluminescence. The photological Njirimara nke nanowires dị ezigbo mkpa maka ngwa ha. The photoluminescence spectra nke ZnO nanowires na ime ụlọ okpomọkụ nwere ike tụrụ na-eji a fluorescence spectrophotometer iji Xe oriọna na excitation wavelength nke 325nm.
2) Diodes na-egbuke egbuke. Site na-eto eto n-ụdị ZnO nanowires na p-ụdị GaN substrates, ìhè-emitting diodes (LEDs) dabere na (n-ZnO NWS) / (p-GaN thin film) heterojunction nwere ike ịmepụta.
3) Mmanụ anwụ anwụ. Site n'iji arrays nke nanowires nwere nnukwu ebe dị elu, ọ ga-ekwe omume ịmepụta mkpụrụ ndụ anyanwụ nke a kwadebere site na organic or inorganic heterojunctions.
3. Njirimara mmetụta nke gas
N'ihi na nke buru ibu kpọmkwem n'elu ebe, na conductivity nke nanowires dị nnọọ mwute mgbanwe na elu kemịkalụ.Mgbe a molekul na-adsorbed n'elu nke nanowire, ụgwọ nyefe pụtara n'etiti adsorbed na adsorbed.The adsorbed ụmụ irighiri nwere ike budata ịgbanwe na dielectric Njirimara nke elu nke nanowires, nke na-emetụta nke ukwuu conductivity nke elu. Ya mere, gas sensitivity nke nanowires e nke ukwuu mma.ZnO nanowires e ji mee conductance sensọ maka ethanol na NH3, yana gas ionization sensọ. , ihe mmetụta pH intracellular, na ihe mmetụta electrochemical.
4. Catalytic arụmọrụ
Otu akụkụ nano-ZnO bụ ezigbo photocatalyst, nke nwere ike decompose organic okwu, sterilaiz na deodorize n'okpuru ultraviolet ìhè irradiation.The ọmụmụ gosikwara na catalytic ọnụego nke nano-sized ZnO catalyst bụ 10-1000 ugboro nke nkịtị ZnO ahụ. ma tụnyere ndị nkịtị ahụ, o nwere ibu kpọmkwem elu ebe na wider ike gbalaga, nke mere ka ọ a ukwuu na-arụsi ọrụ ike photocatalyst na oké ngwa atụmanya.
