Organic Polarized Light-Emitting Transistors.

Electrically Driven Polarized Light-Emitting Sources Are Central to Various Applications Including Quantum Computers, Optical Communication And Three-Dimensional Display, but Remain Serious Challenges Due to The Inevitable Incorporation of Complex Optical Elements in Conventional Devices. Here, Organic Polarized Light-Emitting Transistors (OPLETs), A Kind of Novel Device that Integrates The Functions of Organic Field-Effect Transistors, Organic Light-Emitting Diodes, And Polarizers into One Unique Device, Are Demonstrated with A Degree of Polarization (DOP) as High as 0.97, Which Is Comparable to Completely Linearly Polarized Light (Dop = 1). Under The Modulation of Gate Voltage, Robust And Efficient Polarization Emission Is Proven Ascribed to The Intrinsic In-Plane Anisotropy of Molecular Transition Dipole Moment in Organic Semiconductors And The Open-Ended Feature of OPLETs Instead of Other Factors. In Final, High-Contrast Optical Imaging And Anti-Counterfeiting Security Are Successfully Demonstrated Based on OPLETs, Establishing A New Direction for Photonic And Electronic Integration Towards The On-Chip Miniaturized Optoelectronic Applications.
