“…In the modern world, the development of functional materials with desirable properties is intensely facilitating the fast-growing multi-disciplinary research areas like nonlinear optics (NLO), dielectric, piezoelectric, pyroelectric and ferroelectric, etc [1]. Over the last few decades, the nonlinear optical (NLO) single crystals play an inevitable role in a wide range of technological applications such as lasers, optoelectronics, information processing, optical data storage, optical switching, THz generation and detection, etc [2][3][4].…”
