Optical properties of the crystal violet dye thin film

الملخص EN

Thin films of crystal violet were prepared using dipping method.

The optical properties have been investigated in the spectral rang (300-800 nm) .

The analysis of the spectral behavior of the absorption coefficient α indicate that the fundamental absorption edge arises due to an allowed indirect transition at 1.55 eV assisting phonon of 0.13 eV is also observed.
