TCI C3063 Coumarin 337 is a laser dye from the coumarin family, developed specifically for photonic and optical applications. Unlike coumarin-based materials used as synthetic building blocks, compounds in this class are selected primarily for their strong absorption and fluorescence emission behaviour within particular regions of the spectrum. In the laboratory, this material serves as a gain medium in dye lasers, as a fluorescence standard, and as the active component in studies of optical materials, luminescent thin films, and wavelength conversion systems.

The characteristics that make Coumarin 337 a preferred choice are the high fluorescence quantum efficiency typical of conjugated coumarin derivatives, an adequate Stokes shift between the absorption peak and the emission peak, and good solubility in polar organic solvents such as ethanol, methanol, and dimethyl sulfoxide. The rigid, fully conjugated coumarin structure restricts non-radiative relaxation pathways, so that a greater proportion of the excitation energy is released as light. This property is what has made coumarin dyes a classical reference in luminescence spectroscopy experiments and in the assembly of tunable coherent light sources.

In Indonesian laboratories, this material is typically encountered in university physics and chemistry departments, materials science research groups, and photonics laboratories working on fluorescence measurement and optical characterisation. It is used where a reliable, well-documented emitting dye is needed for calibration work, for preparing dye solutions of defined optical behaviour, or for incorporating a luminescent component into experimental film and device studies supporting thesis research and published work.

  • Dye laser gain medium — dissolved in a polar organic solvent, the dye provides the population inversion needed for tunable coherent emission within its characteristic spectral region.
  • Fluorescence standard and instrument calibration — its well-defined absorption and emission behaviour makes it a stable reference for verifying spectrofluorometer response and comparing quantum efficiency between samples.
  • Luminescent thin film research — the dye can be incorporated into polymer or sol-gel film matrices to study emission behaviour, host-guest interaction, and optical response in solid supports.
  • Wavelength conversion system studies — the Stokes shift between absorption and emission allows excitation light to be re-emitted at a longer wavelength for down-conversion and light-harvesting investigations.
  • Luminescence spectroscopy teaching and method development — as a classical coumarin reference dye, it supports coursework and method validation involving excitation-emission mapping and solvent effect studies.

Storage keep in the original container, tightly closed, protected from light, in a cool and dry place
  • Product Code: C3063

Store the container tightly closed in a cool, dry, well-ventilated area, protected from direct light and away from heat sources, since prolonged light exposure can degrade fluorescent dyes and alter their optical response. Amber glass or opaque, chemically compatible containers are suitable for both the solid material and any prepared solutions. Handle in a fume hood while wearing safety glasses, gloves, and a laboratory coat, and avoid generating or inhaling dust when weighing the solid. Prepare solutions with clean, dry glassware, label them with the solvent and preparation date, and consult the manufacturer's safety data sheet before use and prior to disposal of dye-containing waste.
