Investigation on the Effects of MnCl2 Doping on Structural and Optical Properties of DAST Single Crystals as Materials for Second Order Nonlinear Optics
The intent is to explore the optoelectronic properties of metal ions doped stilbazolium derivative, 4‐N,N′‐dimethylamino‐N‐methyl‐4‐stilbazolium tosylate (MnCl2‐DAST) nonlinear optical crystal materials for the existing technological necessities. The Mn‐DAST single crystals are crystallized by adopting the slow evaporation solution technique (SEST). The structural and crystallographic dimensions of grown crystals are affirmed using single‐crystal X‐ray diffraction and powder crystal X‐ray diffraction. Fourier transform infrared spectra are performed to explicate the functional groups and energy dispersive X‐ray analysis (EDAX) spectra confirm the presence of the chemical elements of grown crystals. The UV–vis absorption spectra of DAST and Mn‐DAST crystals exhibit all possible n–π* and π–π* electronic transitions. The blue shift is observed in the doped materials due to the exchange of lone pair electrons between the metal ions and organic molecule. Tremendously, the second order harmonic generation (SHG) efficiency of Mn (0.01 mol%) doped DAST crystals has 1.68 times larger than that of DAST crystal. From the metal‐organic crystals (Mn‐DAST), all the results brought out are the promising materials in the design of nonlinear optical applications.
