Blog Article

Optical properties of Rhodamine-B thin film prepared by PLD technique have been investigated.The absorption spectra using 1064nm and 532 nm laser wavelength of different laser pulse energies shows that all the curves contain two bands, B band and Q bands with two branches, Q1 and Q2 band and a small shift in the peaks almanac sunshine and opportunity location toward the long wavelength with increasing laser energy.FTIR patterns for Rhodamine-B powder and thin film within shows that the identified peaks were located in the standard values that done in the previous researches.X-ray diffraction patterns of powder stc26 and prepared Rhodamine-B thin film was display that the powder has polycrystalline of tetragonal structure, while the thin film has an amorphous structure.SEM images for Rhodamine-B, shows homogeneous distributed cauliflower-like nanostructures attached with each other.

FM diagram shows that the average grain size was found to be 68.52 nm and the RMS surface roughness was 1.68 nm.
