In this study, it is shown that an efficient organic optocoupler (OPC) can be fabricated using commercially available and solution-processable semiconductors. The transmitter a single-active-layer light-emitting diode (OLED) made from well-known polyparavinylene derivative, Super Yellow. receiver (OLSD) with single active layer consisting of mixture the polymer donor PTB7-Th low-molecular-weight acceptor ITIC; operates without applied reverse voltage. OLED OLSD have same geometry simple structure any interlayers: glass/ITO/PEDOT:PSS/(active layer)/Ca/Al; OPC formed by which adhere tightly to each other. Despite its structure, showed current transfer ratio 0.13%, good linearity, dynamic performance: three-decibel cutoff frequency 170 kHz response times step change in at input 2 μs. Compared most devices similar performance parameters, where complex structures additional interlayers between layers electrodes need apply voltage receiver, design our reduces number fabrication steps greatly simplifies device process.

In situ growth of ultrathin Y2O3 capping layers for Eu-organic thin films via atomic/molecular layer deposition

Journal of Vacuum Science & Technology A Vacuum Surfaces and Films, Год журнала: 2025, Номер 43(2)

Опубликована: Фев. 13, 2025

Metal-organic thin films fabricated through industry-feasible atomic/molecular layer deposition (ALD/MLD) routes are highly attractive materials with diverse functional properties, but they suffer from poor chemical stability in ambient (humid) conditions and especially direct contact liquids which limits their practical implementation. The most efficient way to protect the inherently unstable is encapsulate them chemically inert material layers without exposing metal-organic air during processing. Here, we demonstrate robust situ encapsulation of luminescent ALD/MLD-grown Eu-organic (europium hydroxyquinoline carboxylate) ultrathin (1–12 nm) ALD-grown Y2O3 capping deposited under same conditions. From x-ray reflectivity analysis, successful capping-layer formation only a minor etching effect on underlining film was confirmed despite use strongly oxidizing reactant (O3) for ALD process. Importantly, composition properties were not compromised by etching. encapsulated studied both dry humid air, as well liquid water. results revealed that already 3–4 nm effectively increases when stored open exposed enhanced environment is, particular, critical bioimaging applications.

Development of single-chamber deposition equipment for organic/inorganic nanohybrid composite material

Journal of Vacuum Science & Technology A Vacuum Surfaces and Films, Год журнала: 2025, Номер 43(2)

Опубликована: Март 1, 2025

A newly designed single-chamber system is equipped with Ni/Cr alloy wires that work as the heating filaments in initiated chemical vapor deposition (iCVD) and also RF plasma generating electrode atomic layer (ALD) for facilitating manufacturing of organic/inorganic hybrid thin film encapsulation (TFE). The total processing time was noticeably reduced because temperature ALD could be decreased to iCVD by adopting enhanced (PE-ALD) instead conventional thermal ALD. previously reported using iCVD/ALD processes takes long since substrate temperatures are different cooling steps inevitable between each process. By applying on process, this work, excluded a deposited at same through reactive radical species during PE-ALD multi-layered TFEs have good barrier performance surface single chamber efficiently effectively reduced.
