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).
