Table 1. Fitted PL Lifetimes of Pristine and Heterostructure Samples and Resulting Estimates for ET Efficiencies^a.

intensity	pristine τ₁	heterostructure τ₁′	pristine τ₂	heterostructure τ₂′	η_ET
0.21 W cm^–2	0.456 ns	0.26 ns	3.63 ns	3.64 ns	42%
63.4 W cm^–2	0.62 ns	0.26 ns	2.95 ns	2.9 ns	58%

Fast components of WS₂ PL decay in the heterostructure, τ₁′, and transfer efficiencies, η_E_T, represent upper and lower bound values, respectively, due to limitations in instrument sensitivity. High-intensity excitation values used for comparison with steady-state PL are italicized.
