I have synthesized ZnO nanoparticles. I want to study their fluorescence properties without using spectrofluorimeter. is there any way?
As most of the fluorescent materials are active under long UV (~360 nm), Just to check whether the compound is exhibiting fluorescence or not you can use long wavelength UV light. Commonly used UV chamber can also serves well.
However to study the fluorescence properties you definitely need the instrument.
@Rajkumar, in addition to this, Fluorescent substances absorb the ultraviolet light and then re-emit it almost instantaneously. Some energy gets lost in the process, so the emitted light has a longer wavelength than the absorbed radiation, which makes this light visible and causes the material to appear to glow. Fluorescent molecules tend to have rigid structures and delocalized electrons.
Therefore, you can prefer using UV light as a traditional method.
Check out the work that will help you.
