Abstract Nonlinear optical single crystals of pure l-Alanine (LA) and Zirconium Nitrate-doped l-Alanine (ZNLA) were grown by low-temperature solution growth slow evaporation technique at room temperature. Single crystal and powder XRD confirms the orthorhombic structure. The average crystallite size and lattice strain are 53.21 nm and 0.0048 for LA and 62.17 nm and 0.0041 for ZNLA. FTIR reveals the presence of functional groups in the grown crystal. The optical analysis confirms the high transparency, the obtained direct and indirect transition bandgap of LA and ZNLA are 5.4 eV, 4.84 eV and 5.32 eV, 4.11 eV. The dielectric constant and dielectric loss of the gown materials are low at high frequencies. The relative second harmonic efficiency of l-Alanine and Zirconium Nitrate-doped l-Alanine are 1.15 and 1.47 times higher than that of KDP. The magnetic parameters were identified with VSM analysis. The thermal stability of LA and ZNLA single crystals was found stable up to 193.5 35 °C and 248.35 °C for ZNLA. Photoconductivity reveals that both the material LA and ZNLA have negative photoconductivity nature.
1 Introduction Nonlinear optical single gems have been playing a critical part in numerous logical and industrials applications such as laser, optical information storage devices, optical switching, optical computing, optical communication, optoelectronics, optical modulating, optical limiting, and signal transmission [1–6]. Organic nonlinear optical materials have drawn different fields of research due to high thresholds for laser damage and optical propagation, broad thirdorder nonlinear optical sensitivity and nonlinear coefficient, strong chemical stability, etc. [6, 7]. Amino acid crystals are becoming more and more essential owing to excessive second harmonic nonlinear optical materials [8–10]. To avoid these limitations, researchers have focused on introducing new types of highly optical, thermal, and mechanical properties of single crystals by doping inorganic materials that * M.

generate organic–inorganic complexes [11]. Due to excellent nonlinear optical nature, researchers have reported works on l-Alanine such as l-Alanine Tartrate Single Crystals [12]; Optical, thermal, and mechanical studies on nonlinear optical material diglycine barium chloride monohydrate (DGBCM) single crystal [13]; Growth and characterization of l-Alanine Potassium Nitrate Single Crystals for Nonlinear Optical Applications [14]
