Neuromorphic computing holds the potential to revolutionize traditional computing paradigms, shifting away from the von Neumann architecture towards dynamic, energy-efficient problem-solving. In this talk, I will discuss a new element of photonic neuromorphic computing: Memlumor. It essentially represents a luminescent material with memory. I will show that the metal halide perovskite material class can be used as very efficient Memlumors. The widely considered instability of the physicochemical properties of metal halide perovskites is essential for the operation of Memlumors. To reveal the memory of Memlumors' luminescence, I will additionally present the advanced multi-pulse time-correlated single-photon counting technique. By using this method, I will show the presence of memory in perovskite luminescence over a very wide range of times (from nanoseconds to minutes). The native memory of perovskites, which allows for performing computing operations at the femtojoule energy scale, will revolutionize our perception of luminescence in materials. Further study of memory in the luminescence of different perovskites is essential for making all-perovskite photonic neuromorphic computing processors.
