摘要
We have observed photoluminescence (PL) decay persisting for more than 10(4) s at low temperatures in hydrogenated amorphous Si (a-Si: H). The very-long-lived PL decay was identified by the third peak in the lifetime distribution using frequency-resolved spectroscopy. This residual PL decay fits the derivative of a stretched exponential function and its time integral agrees with light-induced electron spin resonance (LESR) densities. At low temperatures and low generation rates, the monomolecular distant-pair reaction dominates the recombination kinetics at extremely long times after stopping the illumination.
