Summary, etc. <p>A conventional method was adopted to prepare pure ninhydrin (NH) and nickel doped ninhydrin (N1NH) single crystals. The present investigation focused on various properties of as grown NH and NINH crystals. Monoclinic crystal structure with P2<sub>1 </sub>space group which is attractive phenomena were noticed in structural mode of grown NH and NINH crystals. Various vibrations of functional groups related to NH and nickel doped NINH crystals were assigned from Fourier-transform infrared peaks of good resolution. Energy-dispersive X-ray spectrum presents the percentage of carbon, oxygen and nickel occurs in the sample. The strength of the samples have deliberated with the help of Vicker’s microhardness tester. The decomposition point of both NH and N1NH crystals has been measured by thermal analysis. The dielectric constant of both NH and N1NH crystals was also determined. Green emission which denotes second harmonic generation (SHG) process for the samples generally confirms the nonlinear optical (NLO) activity of the NH and N1NH crystals and it has been tested successfully based on the technique of Kurtz-Perry. The SHG efficiency values of NH and N1NH samples are comparable with KDP which has been used as reference sample as it is being used commercially. Basically, NH and NINH crystal samples were used for many medical applications. Therefore, the antifungal activity was also focused for investigation against two famous fungi like <em>Aspergillus niger, Aspergillus flavus</em>.</p>
