Difference between trap assisted and recombination lifetime time?

01 January 1970 0 5K Report

In Time-Resolved Photoluminescence (TRPL) analysis, we often encounter these two terms. The First term is denoted by t1 (Tau 1) and 2nd one by t2 (Tau 2). Also in certain cases, we encounter a third term t3 (Tau 3), what is the physical meaning of t3?

Kindly give your expert opinions.
