In contrast, the absence of quenching of intralayer excitons represents strong evidence of poor interlayer coupling, therefore questioning any further assignments to interlayer species. After establishing that quenched intralayer emission confirms interlayer coupling, we proceed in Figure 1 with step 2 of the protocol, which requires looking for additional excitonic PL signatures in the energy range of the transition corresponding to the expected IX. Here, we want to make sure we distinguish real IXs from artifacts that may be emitting in the same energy range. Specifically, topographical irregularities in the overlap area can cause locally unquenched intralayer exciton emission that may be mistaken for interlayer species. These locally unquenched intralayer excitons are often downshifted in energy due to strain-driven band-gap reduction [41] and can overlap spectrally with IXs. We propose that the risk of strained intralayer excitons and IX overlapping is particularly high when the unstrained intralayer exciton and IX lie within 200 meV, requiring additional analysis. This threshold is 6 not fundamental but reflects typical tensile strains attainable at bubbles or wrinkles and the corresponding exciton shift rates reported for TMDC monolayers [28, 42, 43]. Combining the emission energies with information on intralayer exciton quenching, spatial characterization of emergent PL features, and sample topography is therefore crucial for a correct interpretation of the spectroscop
