The so-called PT symmetric devices, which feature ε (− x)= ε (x)* associated with parity-time
symmetry, incorporate both gain and loss and can present a singular eigenvalue behaviour …

With their exceptional optoelectronic properties, CsPbBr3 perovskite nanocrystals (NCs) are
promising materials for light‐emitting devices. Elucidating their stimulated emission …

Carbon nanodots (CDs) are known to be a superior type of lasing material due to their low
cost, low toxicity, high photostability, and photobleaching resistance. Significant attention …

Mechanically flexible distributed feedback (DFB) lasers are fabricated by a low-cost
approach using soft-lithography from a holographic master grating. The gain material is a …

Optical gain and resistance against photo-bleaching are key material parameters for
practical applications in microlasers and microphotonics. Here, we present studies of optical …

Soluble molecular red emitters 1a/1b are synthesized by Stille coupling from 2‐(3, 5‐di (1‐
