2023年7月1日 · Here, we summarize the research progress on the PL manipulation of the excitonic emission in TMDCs, where the PL intensity enhancement and emission wavelength regulation are included. The concept and characteristics of excitons are overviewed firstly, followed by the discussion on the evaluation and characterization of excitonic emission.

2021年4月2日 · Atomically thin transition metal dichalcogenides (TMDs) have received extensive attention due to their unique electronic band structures and the resulting fascinating physical...

图8.7和8.8是PL为单层MoS2，WS2, MoSe2 and WSe2的PL excitation intensity map，以及PL excitation spectra（红色曲线），relative quantum yield of emission（蓝点）和the differential reflectance spectra（灰色线）之间的比较。通过将积分PL强度除以激发能的吸收来估算相对量子 …

2020年3月9日 · Here, we show that graphene, directly stacked onto TMD monolayers, enables single and narrow-line photoluminescence arising solely from TMD neutral excitons. This filtering effect stems from...

刚刚已经讲过了在tmds中的pl光谱就是发射谱了，这里就不讲了。 不过额外讲一点的是 PLE (photoluminescence excitation)和PL的区别。 PLE是固定发射光的波长，改变激发光的波长，记录荧光强度随激发波长的变化。

2020年2月21日 · The photoluminescence (PL) spectrum of transition-metal dichalcogenides (TMDs) shows a multitude of emission peaks below the bright exciton line, and not all of them have been explained yet. Here, ...
