Isobutylammonium hydrogen oxalate hemihydrate (IHOH), an organic nonlinear optical (NLO) crystal, is developed in this work using a solvent evaporation process. The single-crystal XRD (SCXRD) study reveals the monoclinic system and centrosymmetric space group C2/c of IHOH. The highly crystalline nature of IHOH is confirmed by the presence of well-defined peaks in the powder x-ray diffraction (PXRD) pattern. The presence of various functional groups in IHOH is ascertained by vibrational analysis. The lower cutoff wavelength of IHOH is 223 nm, and it is transparent up to 1100 nm. The refractive index (n), extinction coefficient (k), optical absorption coefficient (α) and optical bandgap (Eg) are determined. Nuclear magnetic resonance (NMR) spectral analysis establishes the molecular structure of IHOH. Z-scanning is employed to analyse the NLO characteristics of IHOH crystal. The crystal demonstrates saturable absorption and a self-defocusing nature. The third-order NLO susceptibility (χ3) of IHOH is calculated as 2.6718 × 10−7 esu. The presence of N–H···O and O–H···O bonds in the IHOH crystal is the reason for the high χ3 value. The photoluminescence (PL) spectrum reveals violet and blue emission from the crystal. The decomposition of IHOH is investigated using thermogravimetry/differential thermal analysis (TG/DTA analysis. The results reveal the suitability of IHOH for Q-switching, optical pulse shortening, optical sensors, and photonic and optoelectronic applications. [ABSTRACT FROM AUTHOR] |
