In our study of CIS-based NCs, a triexponential function IðtÞ ¼ A1et=s1 þ A2et=s2 þ A3et=s3 mathematically converges and better describes (versus a biexponential function) decay curves (i.e., achieves a v2 goodness of fit closer to 1). Lifetime parameters are represented by s1, s2, and s3. A1, A2, and A3 represent the amplitudes of the decay components at t = 0. For
