Integrating sphere charge coupled device-based measurement method for organic light-emitting devices
نویسندگان
چکیده
An integrating sphere charge coupled device ~CCD!-based measurement system has been developed to accurately characterize the optoelectronic performance of organic polymer light-emitting devices ~PLEDs!. By theoretically analyzing a previously developed lens-coupled method and comparing it with the integrating sphere CCD-based method, we have found that the integrating sphere-based measurement method provides more stable reliable optical data in comparison with the lens-coupled measurement method. In addition, we demonstrate that inappropriate calibration of the PLED measurement system can greatly exaggerate device performance. © 2003 American Institute of Physics. @DOI: 10.1063/1.1581394#

Influences of Device Architectures on Characteristics of Organic Light-Emitting Devices Incorporating Ambipolar Blue-Emitting Ter(9,9-diarylfluorenes)
In this article, we report the studies of various device architectures of organic lightemitting devices (OLEDs) incorporating highly efficient blue-emitting and ambipolar carriertransport ter(9,9-diarylfluorene)s, and their influences on device characteristics. The device structures investigated include single-layer devices and multilayer heterostructure devices employing the terfluorene as one...
متن کاملThin-film Encapsulation of Organic Light-Emitting Diodes Using Single and Multilayer Structures of MgF2, YF3 and ZnS
In this research, the lifetime of green organic light emitting diodes (OLEDs) is studied using four passivation layers. To encapsulate the OLEDs, MgF2, YF3, composed of alternating MgF2/ZnS and YF3/ZnS layers were grown by thermal vacuum deposition. Measurements show that the device lifetime is significantly improved by using YF3 and ZnS as passivation layers. However, diodes encapsulated by Mg...
متن کاملLarge-area irradiance-mode spectral response measurements of solar cells by a light-emitting, diode-based integrating sphere source.
An irradiance-mode absolute differential spectral response (SR) measurement system based on a light emitting diode (LED) array is described. The LEDs are coupled to an integrating sphere whose output irradiance is uniform to better than 2% over an area of 160 mm by 160 mm. SR measurements of solar cells when subject to diffuse irradiation, as provided by the integrating sphere, are compared wit...
متن کاملElectronic and excitonic processes in light-emitting devices based on organic materials and colloidal quantum dots
We investigate the mechanism of operation of hybrid organic/colloidal quantum dot light emitting devices QD-LEDs . Novel quantum dot QD deposition methods allow us to change the location of an emissive QD monolayer within a QD-LED multilayer structure. We find that the quantum efficiency of devices improves by 50% upon imbedding QD monolayers into the hole transporting layer 10 nm away from the...
متن کاملLow moisture permeation measurement through polymer substrates for organic light emitting devices
Low permeation measurements through polymer substrates is very critical and there is no definite commercial method for measuring a water vapor transmission rate of 10 gym yday at 39 8C and 95% RH at atmospheric pressure. A novel moisture y6 2 permeation measurement method and model was developed qualitatively and quantitatively with the ‘calcium degradation test’ method. It is well known that o...
