Single-proton tracing in perovskite nanocrystal thin films (thickness, ~15 m) using a fast oscilloscope (Tektronix MDO3024). The count rate of the incident protons was kept low (~500 s -1 ) to avoid overlap of the single-proton signals. The signal of a single proton (amplitude, -30 mV) and the corresponding signal of the proton-induced photon pulses (amplitude, 2.5 V) were recorded, respectively, from channels 1 and 2 of the oscilloscope. In this case, a single proton corresponds to a detectable yield of two photon pulses.
