Abstract

Polymer-confined in situ growth of MAPbBr₃@PAN micro-rings yields cm²-scale composite resonator arrays with highly uniform whispering-gallery-mode lasing. The embedded nanoparticle/polymer architecture enables low-threshold emission, improved humidity stability, and visible wavelength tunability via halide composition control, providing a scalable route to perovskite composite micro-laser arrays.
