摘要：Abstract This work aims at investigating the undoped Glycinium Oxalate (GO) and Manganese doped Glycinium Oxalate (Mn:GO) single crystals that were prepared via slow evaporation method. The single crystals grown were characterized for its structural, vibrational, optical, topographical, electrical and mechanical properties. Single and Powder X-ray diffraction suggests that the grown crystals are crystallized in the monoclinic structure. The functional groups and the effect of moisture on the undoped and doped GO crystals can be analyzed with the help of FTIR spectrum. The undoped and doped GO single crystal shows low absorption in the entire visible and IR region, which is suitable for optical device applications. The emission of green light with the use of Nd:YAG laser (λ = 1064 nm) confirmed the second harmonic generation properties of the grown crystals. Dielectric measurements were carried to the wide range of frequency (50 Hz–5 MHz) at different temperatures. The determined Vickers hardness number and work hardening coefficient of the grown crystals ascertains the soft nature of the crystal.
