ZnO nanowires yog ib qho tseem ceeb heev ib-dimensional nanomaterials.Nws muaj ntau yam kev siv nyob rau hauv lub teb ntawm nanotechnology.Xws li ultra-rhiab heev tshuaj lom neeg nanosensors, dye solar cells, light-emitting diodes, nano lasers thiab hais txog.
Cov khoom tseem ceeb ntawm ZnO nanowires.

1. Kev ua haujlwm ntawm thaj chaw emission
Qhov nqaim thiab ntev geometry ntawm nanowires qhia tau hais tias cov khoom siv hluav taws xob zoo tshaj plaws tuaj yeem ua tau.Txoj kev loj hlob ntawm nanowires tau ua rau muaj kev txaus siab rau kev tshawb nrhiav lawv cov ntawv thov hauv thaj chaw emission.

2. Optical zog
1) Photoluminescence.Cov khoom siv yees duab ntawm nanowires yog qhov tseem ceeb heev rau lawv daim ntawv thov.Lub photoluminescence spectra ntawm ZnO nanowires ntawm chav tsev kub tuaj yeem ntsuas tau siv lub fluorescence spectrophotometer siv lub teeb Xe nrog lub zog siab ntawm 325nm.
2) Lub teeb-emitting diodes.By loj hlob n-type ZnO nanowires ntawm p-type GaN substrates, lub teeb-emitting diodes (LEDs) raws li (n-ZnO NWS) / (p-GaN nyias zaj duab xis) heterojunction yuav fabricated.
3) Roj hnub ci hlwb.Los ntawm kev siv arrays ntawm nanowires nrog cov cheeb tsam loj, nws tau ua tau los tsim cov roj hnub ci hlwb npaj los ntawm cov organic lossis inorganic heterojunctions.

3. Gas rhiab yam ntxwv
Vim hais tias ntawm qhov loj ntawm qhov chaw, cov conductivity ntawm nanowires yog heev rhiab heev rau cov kev hloov nyob rau hauv nto chemistry.Thaum ib tug molecule yog adsorbed rau saum npoo ntawm nanowire, tus nqi hloov pauv tshwm sim ntawm cov adsorbed thiab cov adsorbed.Qhov adsorbed molecules muaj peev xwm hloov tau ntau yam. Cov khoom dielectric ntawm qhov chaw ntawm nanowires, uas cuam tshuam rau cov conductivity ntawm cov nto.Yog li ntawd, cov roj rhiab heev ntawm nanowires tau zoo heev.ZnO nanowires tau siv los ua conductance sensors rau ethanol thiab NH3, nrog rau cov roj ionization sensors. , intracellular pH sensors, thiab electrochemical sensors.

4. Catalytic kev ua tau zoo
Ib-dimensional nano-ZnO yog ib tug zoo photocatalyst, uas muaj peev xwm decompose organic teeb meem, sterilize thiab deodorize nyob rau hauv ultraviolet lub teeb irradiation.Cov kev tshawb fawb kuj pom tau hais tias tus catalytic tus nqi ntawm nano-loj ZnO catalyst yog 10-1000 npaug ntawm cov zoo ZnO hais, thiab piv nrog cov khoom zoo tib yam, nws muaj thaj tsam loj dua thiab dav dua lub zog, uas ua rau nws muaj zog photocatalyst nrog kev thov zoo.
