Description
TCI C3072 Coumarin 510 is a coumarin-class laser dye developed for applications in photonic and optical materials research. Compounds in this class act as active chromophores that absorb light within a specific wavelength range and re-emit it as fluorescence with high efficiency. In the laboratory, materials of this type are used in dye laser assembly, spectrofluorometric measurement, the preparation of luminescent films, and a broad range of photochemical experiments that require a bright, stable emission source whose concentration can be readily controlled in organic solvents.
The characteristics that make Coumarin 510 a preferred choice are its conjugated and rigid coumarin framework, which minimises energy loss through non-radiative pathways and therefore produces strong luminescence. Coumarin derivatives generally exhibit an adequate Stokes shift, so the emission peak is clearly separated from the absorption peak, making measurements easier to perform without interference from scattered excitation light. Its good solubility in polar organic solvents such as ethanol and dimethyl sulfoxide simplifies the preparation of stock solutions as well as serial dilutions, while its polarity-sensitive emission behaviour offers an additional experimental variable.
In Indonesian laboratories, a dye of this type is typically used in university photonics and materials science groups, government research institutes, and industrial optical laboratories. It supports teaching and research work in fluorescence spectroscopy, tunable laser demonstrations, and the development of light-emitting thin films and optical coatings. Because it is supplied as a defined TCI catalogue item, it can be incorporated into documented experimental procedures and repeat orders without changing the material specification between studies.
Laboratory Applications
Dye laser assembly and tuning, where the high fluorescence efficiency of the coumarin chromophore provides a bright and stable gain medium in the blue-green emission region.
Spectrofluorometric measurement and instrument calibration, since the well-separated absorption and emission peaks allow reliable readings without interference from scattered excitation light.
Preparation of luminescent films and optical coatings, where the dye can be dispersed in a matrix to produce a defined fluorescent response for characterisation studies.
Photochemical experiments requiring a controllable emission source, because solubility in polar organic solvents makes stock solutions and serial dilutions straightforward to prepare accurately.
Solvent polarity and microenvironment studies, taking advantage of the polarity-sensitive emission behaviour of coumarin derivatives to probe local conditions within a sample system.
Pack sizes: available in the standard TCI catalogue pack sizes for this item; please confirm the size required when ordering.
Storage: keep in a tightly closed container, protected from light, in a cool and dry place.
Handling and Storage
Store the material in its original tightly closed container, protected from light and moisture, in a cool, dry, and well-ventilated area away from strong oxidising agents and ignition sources. Amber glass or otherwise light-protected containers are suitable for prepared stock solutions, which should be clearly labelled with the solvent and preparation date. Handle the dye in a fume hood or a well-ventilated workspace, and wear a laboratory coat, gloves, and safety glasses to avoid contact with skin and eyes and inhalation of dust when weighing the solid. Avoid generating dust during transfer, close the container promptly after use, and dispose of residues and contaminated materials in accordance with the applicable laboratory chemical waste procedures. Always consult the manufacturer's safety data sheet before use.
