Halide perovskites, with high luminescence efficiency, tunable bandgaps, and compatibility with low-temperature processing and micro/nanostructuring, are a promising platform for anti-Stokes cooling. A central challenge is to enhance both pump absorption and the anti-Stokes radiative channel at the micro/nanoscale while suppressing losses, paving the way toward practical, integrated perovskite laser coolers. Together, these dual resonances enable simultaneous optimization of the absorption–emission cycle, offering a new structural route to improve laser-cooling efficiency.
