Using ZnO gain phenomenological model, the spectrum characteristics and spatial distribution of optical field in ZnO nanorods random media is simulated numerically by means of the finite difference time domain method, the localized mode is found. Firstly using Gaussian pulse in ZnO two-dimensional random media, five typical resonance peaks of observation point occur in ZnO gain range, the spatial distribution of optical field presents localization characteristics in the random media is found. Then using sinusoidal wave instead of Gaussian pulse, The optical field corresponding to the resonance peaks is discussed. We found the optical field of different localized mode has different spatial distribution.","PeriodicalId":222199,"journal":{"name":"Advances in Optoelectronics and Micro/nano-optics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123152152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking a two-dimensional grating as an example, the modeling method using the rigorous coupled-wave analysis theory has been described. The Mueller matrix elements are obtained with different measurement configurations, such as changing the wavelength and azimuthal angle. It is observed that different geometrical parameters show variable sensitivities even under a fixed measurement configuration, and more information is achievable by changing the configuration. It is thus verified that it is feasible and effective to characterize nanostructures by the Mueller matrix polarimetry.","PeriodicalId":222199,"journal":{"name":"Advances in Optoelectronics and Micro/nano-optics","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121002563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For PLED, there is a large energy barrier for hole injection with commonly used indium tin oxide (ITO) as anode. With a thin layer of NiO deposited on ITO, the energy barrier was decreased because of the higher work function of NiO than ITO, which facilitated hole injection. Therefore, the balance of electron and hole current was improved and also PLED performances. Experimental results also showed that the PLED performances were very sensitive to the thickness of NiO. Thick NiO layer led to the reduction of device current density, and therefore, poor PLED performances because NiO has a higher resistivity value than that of ITO. It turns out that 1 nm is the optimal thickness of NiO among 1, 2, 4 and 8 nm to produce high efficiency PLEDs. After the insertion of 1 nm NiO, the maximum electroluminescence intensity of PLED was almost doubled.","PeriodicalId":222199,"journal":{"name":"Advances in Optoelectronics and Micro/nano-optics","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124810885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Al-doped ZnO (ZAO) thin films were prepared by RF magnetron sputtering technology. We realized ZAO films with the better performance by adjusting and optimizing the sputtering gas pressure and substrate temperature. Using UV-vis spectrophotometer tested the ZAO film optical performance, which indicates that the samples prepared at 5∼10 Pa sputtering gas pressure have the visible light transmittance above 85 %, but transmittance of the prepared samples at sputtering gas pressure of 1∼4 Pa is below 80 %. The average transmittance of the samples prepared at 250 and 350, 400 °C substrate temperatures did not change obviously and were more than 85%. However, with the further increase of substrate temperature, the transmittance began to fall. Especially, the transmittance of the samples prepared at 500°C decrease below 75%.
