摘要

High-quality methyl orange dye-doped adipic acid single crystals were harvested successfully at ambient temperature by solvent evaporation route. SXRD, PXRD, FT-IR and EDAX examination confirms the small appreciable amount of entry of dopant species in the grown crystalline matrix. Transmittance percentage of UV spectrum was suddenly dipped around 480–490 nm (n to π* transition peak) due to the occurrence of methyl orange dye absorption peak. Kurtz NLO experiment confirms decline in second harmonic generation efficiency value. The melting temperature is augmented in TG–DTA thermograms. Methyl orange dye MO-doped adipic acid crystals show potential for optoelectronic devices, acting as optical filters due to dipped transmission percentage and superior decomposition points, demonstrating increased thermal resilience for practical applications.
