Single-mode lasing of CsPbBr perovskite NWs enabled by the Vernier effect
Inorganic lead halide perovskite (CsPbX 3 , X = Cl, Br, I) NWs (NWs) have been employed in lasers due to their intriguing attributes of tunable wavelength, low threshold, superior stability, and easy preparation. However, current CsPbX 3 NW lasers usually work in a multi-mode modal, impeding their p...
