Induced neodymium luminescence in sol–gel derived layered double hydroxides

The Mg₃Al_1−xNd_x layered double hydroxides (LDHs) were synthesized via aqueous sol–gel synthetic route and the influence of the Nd³⁺ doping on the Mg₃Al_1−xNd_x LDHs properties was estimated for the dopant concentration varied in the range of 1–10 mol%. The microstructure and morphology of the synthesized LDHs were revealed by X-ray diffraction analysis and scanning electron microscopy. The neodymium doped LDHs were characterized by the luminescence emission spectra.
