Abstract
Photoluminescence quantum yield (PLQY) is an important characteristic of luminescent materials. Photoluminescence (PL) is light emitted by a luminescent material after absorbing photons. Quantum yield (QY) is defined as the number of times a specific event occurs per photon absorbed by the system, Transition metal dichalcogenide (TMD) is a kind of material with the type of MX2. TMD is a semiconductor material, but also a two-dimensional material. Single-layer TMD has the properties of large exciton and trion binding energy, which are appropriate in the development of optoelectronics. PLQY is a good method to measure the optoelectronic properties of TMD materials
