Gold layer with thickness 300, 400, 500, 700, 1000, 1300, and 1500 nm were deposited to prepare Au / PM-355 thin films. Then, ac electrical properties response of thin films for a wide frequency range 20Hz - 5MHz were measured at room temperature. Meanwhile, the measurements of ac conductivity, dielectric constant, and dielectric loss factor were plotted at different frequencies to determine the optimum thickness. Hence, the comparison was done between optimum Au thickness thin films cleaned by two organic solvents and ethanol before annealing at different frequencies. Also, study the effect of annealing and ion beam that extracted radially from conical anode and disc cathode ion source on optimum Au thickness thin film electrical properties. It is found that the annealing increases both dielectric constant, dielectric loss, and ac conductivity of optimum Au thin film at different frequencies. Despite, the nitrogen ion beam effected on these thin films by decreasing the dielectric constant and ac conductivity for all thin films except the chloroform one. Finally, study the comparison between the annealing and followed by ion irradiation thin films. It is noticed the decrease in ac electrical conductivity and dielectric constant at different frequencies.","PeriodicalId":209214,"journal":{"name":"Indian Journal of Pure & Applied Physics","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121942662","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}

FWHM or line-width of the resonance power absorption peaks is calculated using profile method and the influence of magnetic field, temperature and thickness of the FSNS is investigated, that the line-width is proportional to magnetic field whereas it is independent of temperature and thickness of FSNS.

We report here the fabrication of organic light emitting diodes (OLEDs), which emit white light via multilayer color approach. These WOLEDs incorporated the materials emitting two complementary colors greenish-blue and reddish-orange to make white. The amount of light emitted from each layer was chosen in such a way that the mixture of the two emitted lights gave white light. The amount of light emitted from each layer was controlled by taking optimum thickness of each layer and incorporating a thin hole blocking layer of BCP in between the emissive layers. For greenish-blue light, we used a phosphorescent dopant FIrPic whereas for reddish-orange light we used the phosphorescent dopant Ir(btp) 2 (acac) and both of these dopants were doped in the host CBP. We studied the effect of operating voltage on the color of the emitted light of these WOLEDs and found that the color of the emitted light was almost independent of operating voltage. The WOLEDs emitted 1600 cd/m 2 at 15 V with Commission Internationale de I’Eclairage (CIE) coordinates (0.25, 0.32). We also studied the current density vs voltage ( J-V ) and voltage vs luminescence ( V-L ) characteristics of these devices and calculated their efficiency which was found to be 0.35 cd/A. We also prepared some WOLEDs based numeric displays just of the demonstration purpose.","PeriodicalId":209214,"journal":{"name":"Indian Journal of Pure & Applied Physics","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121934933","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}
