“…Concerning the applicability of R6G dye, there was a need to use some other method in which the limitations stated above can be overcome. One such technique used is thermal evaporation of the dye onto various substrates to use them more effectively in opto-electronic device formulation [14]. This technique would only be helpful if the molecule of R6G does not dissociate on being thermally heated and evaporated.…”

The present paper reports the study of Rhodamine 6G (R6G) in thin film form and its structural, optical and electrical characterization. The R6G films are found to have an amorphous structure as determined using the x-ray diffraction technique. The FTIR spectra of R6G thin film confirms that this molecule does not dissociate on being thermally evaporated and thus this technique can be used to deposit the thin films. The fluorescence and transmission spectra, of the thin film, show a redshift in peaks. Temperature dependence of dark conductivity (σd) and photoconductivity (σph) measurements, in the temperature range 303–403 K, confirms that the conduction in R6G is through an activated process having a single activation energy. The photoactivation energy (Eph) value is smaller in comparison to the activation energy in dark (Ed).

Evaporated dye layers are gaining in importance in modern information and energy storage systems due to their specific optical and electrical properties. The photophysical properties decisively depend on the structure of layers, e.g., on a kind of aggregation, degree of crystallinity and crystal modification. These parameters and, therefore, the properties can be strongly manipulated by technological parameters (kind and temperature of substrate, evaporation rate, annealing) and by coevaporated admixtures of inorganic (metal halides or oxides) or organic (dyes or others) compounds. On the basis of recent investigations of evaporated merocyanine and phthalocyanine dyes, some results of the relationship between deposition are presented technology, structure and photophysical properties and evaluated with regard to their usefulness in organic solar cells.
