Organic Non- linear optical single crystals with the second harmonic generation values are useful in optical communication and signal processing in integrated optics. Rhodamine is a dye, an organic molecule well-studied in laser physics and nonlinear optics for its fluorescent properties. In the present work, a new organic rhodamine dye doped Butylated hydroxy toluene (DBHT) single crystals were grown by slow evaporation technique. The lattice parameters of the grown crystals are found from single crystal XRD analysis. The FT-IR analysis confirms the presence of various functional groups available in DBHT. The dielectric analysis can be used to find the electrical properties of DBHT single crystal as a function of temperature and frequency. The optical studies carried out reveal that the DBHT crystals exhibit good optical quality and possible NLO applications. The thermal and mechanical stability of the crystal is studied by TG/DTA analysis and Vicker__ampersandsignrsquo;s microhardness test.
