A normal way of slow evaporation method had been used to preparing pure ninhydrin (PN) and magnesium doped ninhydrin (M1N) single crystals. The research describes the various characterizations of the developed PN and M1N crystals. Monoclinic crystal structure with non centrosymmetric P2₁ space group were marked in the developed crystals. Additionally, to find out the various functional groups of the grown PN and M1N crystals Fourier’s transformation infra-red studies had been used for this research. Vicker’s microhardness tester had been used to identify the strength of the developed crystals. In energy dispersive x-ray analysis the presence of carbon, oxygen and magnesium into the crystal lattice was observed. In connection with this by using thermal analysis the decomposition point of the developed crystals were marked. The photoluminescence study was used to identify the excitation and emission peaks of the grown samples. Conclusively, by powder Kurtz-Perry method the second harmonic generation efficiency had been verified in a greater aspect of this research. The antifungal activity of the PN and M1N crystals was observed against two fungi such as Aspergillus flavus, Aspergillus niger.

镁掺杂的茚三酮晶体的增强的机械，热，光致发光，NLO和抗真菌活性

已使用正常的慢速蒸发法制备纯茚三酮（PN）和掺杂镁的茚三酮（M1N）单晶。该研究描述了已开发的PN和M1N晶体的各种特性。非中心对称P2 _1的单斜晶体结构在已发展的晶体中标记了空间群。另外，为了找出生长的PN和M1N晶体的各种官能团，本研究使用了傅里叶变换红外研究。使用了维氏显微硬度测试仪来鉴定已开发晶体的强度。在能量色散X射线分析中，观察到碳，氧和镁进入晶格。与此相关，通过使用热分析，标出了所形成晶体的分解点。光致发光研究用于确定生长样品的激发和发射峰。最后，在本研究的更大范围内，通过粉末Kurtz-Perry方法验证了二次谐波的产生效率。黄曲霉，黑曲霉。
