Type of data	Graphs and Figures
How data was acquired	•CL spectra was acquired from measurements in a Gatan mono-CL system in UV–Vis range coupled with scanning electron microscope (JSM-7800F, JEOL). •RB loading percentage was determined using UV–vis Cary 60 spectrophotometer. •PL spectra were obtained using a fluorescent spectrophotometer (Hitachi F-7000) equipped with a 150 W Xenon lamp.
Data format	Filtered
Experimental factors	•The as-synthesized nanoparticles were annealed at 1100 °C for 3 h before any further usage. •The samples for TEM analysis were prepared by 15 min ultrasonic dispersion of nanoparticles in isopropanol. Histogram of particle size distribution was acquired from diameter of 80 different images of nanoparticles obtained from TEM.
Experimental features	The sol–gel synthesized GAG nanoparticles were coated with mesoporous silica and later, RB was loaded inside these mesopores. Finally, ROS generation upon exposure with blue light was confirmed by DPBF assay.
