“…Most of noncentro/symmetric crystals have a high 2nd harmonic generation (SHG) efficiency surpass centrosymmetric ones. Centrosymmetric crystals possess a remarkable 3rd nonlinear optical behaviors made them right choice for optical sensing, switching, and limiting processes (Amudha et al 2017a, b;Karuppanan and Kalainathan, 2018;He et al2018). The seek for improving their photoconductive characters are carried by tailoring their band offsets (El-Nahass et al 2013;Ibrahim et al 2012Ibrahim et al , 2013Soliman et al 2013) to facilitate electrons rush across conduction domain.…”

Both theoretical and experimental studies are briefly discussed to shed lights on crystal shape, FT-IR, electronic, and non-linear opto-response (NLO) characteristics of ethyl4-(3,4-dimethoxyphenyl)-6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (MTTHPC). Theoretical FT_IR results are in a proper concord with recorded measurements. MTTHPC has TDM (4.78 Debye) and a doublet spins that splits original FMOs into alpha(↑, 2.44 eV) and beta(↓, 1.28 eV) offsets, respectively. MTTHPC is a potential competitor for finest perovskite solar cells (MAPbI 3 /Au-nanospheres) that possess a band offset ( 3.1 eV ) with conversion-efficiency 24.84%. MTTHPC may be the next chapter for unique avalanche photodetectors (APD). MTTHPC 1st order hyperpolarizability is 14.15 * 10 −30 esu , surpass reference urea (≈ 40 urea , urea = 0.3728 * 10 −30 esu ). Briefly, MTTHPC may be admitted as the next stage in forthcoming NLO technology.
