Indium Doping

Effects of indium doping (concentration 0.2, 0.3 and 0.4%) on the optical properties of GaAs thin films were studied. Thin films of 600 nm were grown onto chemically and ultrasonically cleaned glass substrate by thermal evaporation method in high vacuum (~10-4 Pa) at 50°C fixed substrate temperature. The samples were annealed for 15 minutes at a fixed temperature of 200°C. The thicknesses of films were being measured in situ by a quartz crystal thickness monitor during deposition. The transmittance and reflectance data were found using UV-VIS-NIR spectrophotometer in the photon wavelength range of 310 ~ 2500 nm. These data were utilized to compute the absorption coefficient, refractive index, extinction co-efficient and band gap energy of the studied films. Here transmittance was found 78 for 0.2% indium doping concentration. The band gap energy decreased with the increase of doping concentration.Journal of Bangladesh Academy of Sciences, Vol. 40, No. 2, 179-186, 2016

Red Dye

Multilayer chroma stability of white OLEDs was realized with blue dye DPVBi and red dye DCJTB doped as luminescence layer. The blue dye doping concentration was kept at 6%, at the same time the red dye was reduced from 4%, 2%, 1% to 0.5%. The device color coordinates (CIE) were adjusted from (0.58, 0.42) to (0.31, 0.32), achieving the white light emission. A stable white emission for forward bias voltage changes from 6 to 17 V has been achieved. Its maximum luminance was 15030 cd/m2 at 17 V, and the maximum current efficiency was 4.65 cd/A at 9 V. We contributed the main reason of chroma stability to the complete energy transfer from CBP to DCJTB and the incomplete energy transfer between DPVBi and DCJTB by analyzing the spectrum and characteristic of the device so its performance was enhanced.
