Semi-organic acid mixed glycine nitrate crystal (GPCN) for photonics applications has been synthesized and grown in bulk from an aqueous solution with pH 4.8 at room temperature. Transparent crystals measuring 8 x 6 x 4 mm³ were obtained over a period of 2-3 weeks. The solubility of GPCN in water was determined, and the chemical composition of the crystals was confirmed through CHN and EDAX analysis. The crystals were characterized using powder XRD, FTIR, and UV spectroscopy. The GPCN crystals belong to the orthorhombic system, with cell parameters a = 14.827 Å, b = 13.287 Å, c = 9.954 Å, and a unit cell volume of 1961.30 ų. The presence of fundamental functional groups was verified and UV studies revealed a wide transparency window with a cutoff wavelength at 216 nm, making it suitable for optoelectronic applications. The second harmonic generation (SHG) efficiency of GPCN was found to be 0.66 times that of KDP when using a 1064 nm Nd:YAG laser, as per the Kurtz and Perry method have been carried out.
