A hybrid nanolaminates consisting of Al 2 O 3 /ZrO 2 /alucone (aluminum alkoxides with carbon-containing backbones) grown by atomic layer deposition (ALD) were reported for an encapsulation of organic light-emitting diodes (OLEDs). The electrical Ca test in this study was designed to measure the water vapor transmission rate (WVTR) of nanolaminates. We found that moisture barrier performance was improved with the increasing of the number of dyads (Al 2 O 3 /ZrO 2 /alucone) and the WVTR reached 8.5 × 10 −5 g/m 2 /day at 25°C, relative humidity (RH) 85%. The half lifetime of a green OLED with the initial luminance of 1,500 cd/m 2 reached 350 h using three pairs of the Al 2 O 3 (15 nm)/ZrO 2 (15 nm)/alucone (80 nm) as encapsulation layers.

Narrow Bandwidth Top-Emitting OLEDs Designed for Rhodamine 6G Excitation in Biological Sensing Applications

Organic light emitting diodes (OLED) are promising candidates offering in optical sensor applications to detect different gas compositions and excitable optical marker groups in chemical and biological processes. They enable attractive solutions for monitoring the gas phase composition of e.g., dissolved molecular oxygen (O2) species in bio reactors or excitation of fluorescent markers. In this work, we investigate different OLED devices for biomedical applications to excite the fluorescent dye rhodamine 6G (R6G). The OLED devices are built in top emission geometry comprising a distributed Bragg reflector (DBR) acting as optical mirror. The OLED is optimized to provide a very narrow emission characteristic to excite the R6G at 530 nm wavelength and enabling the possibility to minimize the optical crosstalk between the OLED electroluminescence and the fluorescence of R6G. The DBR includes a thin film encapsulation and enables the narrowing of the spectral emission band depending on the number of DBR pairs. The comparison between optical simulation data and experimental results exhibits good agreement and proves process stability. OPEN ACCESSElectronics 2015, 4 983

“…Additionally, disposability of OPDs and hybrid PDs is not expected to be a major problem due to potential future low cost of such devices. Moreover, encapsulation approaches to minimize adverse effects of moisture and O2 are available as was developed for OLEDs [94][95][96], which will extend the operational lifetime of the OPDs. Short wavelength irradiation is known to adversely affect solar cells [97], though this is less of an issue for OPDs that are typically exposed to lower intensity longer wavelengths.…”

This review focuses on the utilization of organic photodetectors (OPDs) in optical analytical applications, highlighting examples of chemical and biological sensors and lab-on-a-chip spectrometers. The integration of OPDs with other organic optical sensor components, such as organic light emitting diode (OLED) excitation sources and thin organic sensing films, presents a step toward achieving compact, eventually disposable all-organic analytical devices. We discuss recent advances in developing and integrating OPDs for various applications as well as challenges faced in this area.
