High-Performance White Emission Polarized Single Crystal and Device

• • Co-doping DPA single crystals with 3% Tc and 0.5% Pen yields white emission with a PLQY of 38.3%, enabling efficient intrinsically polarized white light sources for displays and optical communication. • • The degree of polarization (DOP) reaches 0.96 at 450 nm, 0.71 at 500 nm, and 0.69 at 610 nm, providing high polarization purity essential for 3D displays and quantum computing. • • Large-scale fabrication on a 0.9 cm × 0.9 cm silicon wafer demonstrates scalability, addressing a critical bottleneck in manufacturing miniaturized polarized OLEDs. • • X-ray diffraction confirms that the bc crystal plane is parallel to the substrate, ensuring uniform in-plane crystal orientation and consistent polarized emission across the device area.
