Fluorescence is a fascinating powerful spectroscopic technique. It deals with Chemistry, Physics and Light. It takes advantage of the ability of molecules and atoms (organic & inorganic) to interact with the electromagnetic waves of light, these interactions have allowed scientists to go deep into molecules and atoms, explore them further and gain insight into their electronic properties since Fluorescence is the result of electrons’ relaxation. The fundamental basis of Fluorescence is the detection then the sorting of the electromagnetic waves emitted by excited electrons during their return to the normal not-excited state called “ground state”.
It’s a very sensitive tool, it’s roughly 1000 times more sensitive than absorption spectrophotometric methods. Its Limit Of Detection (LOD) can reach the picograms of concentration. These properties among others have made of the Fluorescence an essential technique in studying and developing new photoluminescent (photoactive) materials such as:
- Organic Light Emitting Diodes (OLEDs)
- Photovoltaic Cells (PVs)
- Imaging probes
- Sensors (pH, T, polarity, morphology, sizes,…)
Besides its sensitivity, it may also be used as a specific detection method in chemical & food analysis when a specific target with known photoluminescent properties is the subject of the study or analysis.
At LuminoChemi, we have a long story with Fluorescence and would love to help and train you using it, studying your materials, implementing it in your lab/company and build research projects where it plays an important part. We carry out photophysical investigations, steady-state and time-resolved measurements in solution and in the solid state (KBr pellets, PMMA, Polystyren,…)
