Sub-wavelength single-mode all-inorganic perovskite CsPbBr3 nanolaser

摘要

We report the single-mode, high-quality, low-threshold picosecond pulses laser whose physical volume is only ～0.49 λ~3 (where λ is the lasing wavelength in air) from an individual all-inorganic perovskite CsPbBr~3 nanocuboid.
