Abstract: Influence of amaranth dye on the potassium hydrogen oxalate oxalic acid dihydrate (KHOOD) single crystal is investigated. The structural studies were carried out to understand the crystal behavior after dye incorporation. Optical studies were performed to investigate the photon absorption of the crystal with or without the presence of dye molecule. The absorption of pure crystals were also compared with that of amaranth dye-doped crystals and the bandgap was estimated. The surface morphology and the presence of dye molecules are investigated using scanning electron microscope (SEM) and EDX analysis. The elemental mapping was carried out to understand the distribution of elements in the crystal surface. The thermal behavior of the crystal was studied and compared with that of KHOOD and dye-doped KHOOD crystals in detail. The emission properties of the crystals were studied and compared crystal. Field-dependent I-V studies were performed to study the conductivity of the crystals and results were discussed in detail. 2020 World Scientific Publishing Company.
