Abstract
Inorganic lead halide perovskite nanocrystals (IHP NCs) are known for their exceptional photoluminescence efficiency. This presentation will explore their capacity for converting thermal energy into light via one-photon optical upconversion, or anti-Stokes photoluminescence (ASPL). ASPL is pivotal for advancing "thermophotonic" technologies where highly luminescent semiconductors transform heat into light, driving various thermodynamic engines.
