Dear Jitesh Pandya , you can monitor the PL intensity variations of a solid sample like a perovskite film using Front-Face photoluminescence spectroscopy. It is usually carried out with a conventional spectrofluorimeter equiped with a Front-Face accessory. In this way, you can scan the emission spectrum in succession and investigate the effect of moisture on PL emission over time. Moreover, if you do not have access to a front-face accessory, you can also take advantage of a plate reader in order to scan the PL emission of the surface. If still do not have access to any of these, you can use a UV cabinet and take several photos in succession. By extracting the RGB values you may investigate the PL variations over time. The following question has thoroughly discussed the front-face PL spectroscopy. Attached you may also find a picture illustrating how the front-face accessory works.
