Improving Photoluminescence Emissions and Photostability of Dye/MgAl‐Layered Double Hydroxide Nanohybrids

Abstract

AbstractThe purpose of this study was the preparation of layered double hydroxide (LDH) ‐based nanohybrids with improved photoluminescence emission and high photostability. The anion exchange‐based microwave method was applied for the intercalation of mordant orange 1 into MgAl‐LDH. The prepared organic‐inorganic nanohybrid was confirmed by X‐ray diffraction, thermal gravimetric analysis (TGA), inductively coupled plasma spectrometry (ICP), and infrared spectra (FT‐IR). Also, the morphology of the obtained sample was investigated using the field emission‐scanning electron microscopy (FE‐SEM) method. In the MgAl‐LDH interlayer space, a tilted orientation and bilayer arrangement were predicted for the mordant orange 1 anions. Compared with the pure mordant orange 1, the MgAl‐LDH/mordant orange 1‐MA (prepared using the microwave‐based anion exchange method) has improved photoluminescence emission with high Photostability. These findings supply a new approach for designing photoluminescence materials that potentially apply to optical devices with high Photostability.
