The well-known medical participation of AZO dye industry derivatives in the use of vital brilliant red dye acts as an anticonvulsant. The AZO dyes permeability through the blood–brain barrier was found to be a factor in the development of a vast variety of chronic neurological diseases. Because of the potential influence on the environment and human health, the presence of AZO dyes in textile effluents is a major concern. Under visible light, we analyze the photocatalytic degradation of AZO dyes, which are widely utilized in the textile sector. In the present analysis, the properties of combustion-formed mixed sulfide solids were investigated in solutions which are supersaturated simultaneously with dysprosium and erbium. The Sr_1-xCu_xSO₄ nanoparticles arrangement acts as a step for dysprosium and erbium co-doping based on the interactions between thiourea. The phase structure and sample states obtained of the stimulant components be analyzed by Field emission scanning electron microscopy (FESEM), High-resolution transmission electron microscopy (HR-TEM) and photosynthetic studies with X-ray powder diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). Additional data analysis by Rietveld refinement allowed the exposure of a smaller lattice parameter and volume increase related to the absorption of stimulant components. Integrated Sr_1-xCu_xSO₄ co-doped Dy³⁺, Er⁴⁺ showed effective photosynthetic presentation at some stage in decomposition of organic dyes (Acid Black 1, direct blue 15), and hydrogen production from water under ultraviolet light. In addition, Dy, Er co-doped was also deposited and their photosynthetic activities were examined. The consequences and impact on neurology are also examined in this article.
