In this study, we investigated the photoluminous spectroscopic behavior of hybrid powder incorporating both anionic fluorescein dye (AFD) and 1-butanesulfonate (C4S) with layered double hydroxide (LDH) in the presence of NH3 or NO2 gas under various relative humidity conditions. In the presence of NH3 gas, drastic photoluminescence enhancement from the LDH/AFD/C4S hybrid was observed at relative humidity (RH) ≥ 40% when the NH3 reached a certain concentration. Meanwhile, the LDH/AFD/C4S hybrid was exposed to NO2 gas at various relativ
