Description
Summary:[Display omitted] •Organic 2,7-dihydroxy naphthalene crystal was grown using organic solvent.•2,7-Dihydroxy naphthalene crystal is transparent over the entire UV–Vis–NIR region.•The grown crystal belongs to orthorhombic crystal system.•2,7-Dihydroxy naphthalene crystal is insoluble in water, non-hygroscopic and high resistive. The organic nonlinear optical crystals of 2,7-dihydroxy naphthalene (2,7-DN) were grown by slow evaporation method using acetone as a solvent. Optically transparent single crystal with sizes up to 15×7×4mm3 were grown. Non-centrosymmetry has been studied using X-ray diffraction (XRD) and functional group of 2,7-DN were studied by Raman scattering and FTIR spectral analysis. The optical transmittance was characterized and to be 28%. The melting point of 2,7-DN is 465K. 2,7-DN found exhibit low dielectric constant of 20–22 in the frequency range of 10Hz–10MHz at room temperature. The nonlinear optical and phase matching properties were characterized by Kurtz powder second harmonic generation (SHG) efficiency test.
