  1. a1, 2, 3 stand for [Au28(p-MBT)14(Hdppa)3](SO3CF3)2, [Au21(m-MBT)12(Hdppa)2]SO3CF3, and Au30S(S‑t‑Bu)18 respectively. PLQY is photoluminescence quantum yield. τavg is average lifetime. kr is radiative decay rate, knr is non-radiative decay rate. kr and knr are calculated according to Eqs. (1) and (2).
