Perovskite light‐emitting diodes (LEDs) emitting in the pure‐red range of 630–640 nm show promise in meeting the requirement of the Rec.2100 standard for high‐resolution displays. However, the high‐performing LEDs (external quantum efficiency, EQE >20%) in the pure‐red range suffer from half‐life time (luminance drop to 50% of the initial luminance) of <1.6 h, resulting from the injection/transportation...
Plasmonic materials have aroused considerable interest in diagnostic and therapeutic biomedical applications because of their remarkable optical properties and the integration of multiple functionalities. Particularly, near‐infrared II (NIR‐II) plasmonic materials present great advantages for anticancer treatments, including deep tissue penetration, low tissue light scattering and autofluorescence,...
