Abstract

The aim of the research is to look at how to characterise Rubidium chloride (RbCl) doped magnesium oxide (MgO) nanoparticles synthesized from grape juice. Rubidium chloride is an excellent water soluble crystalline rubidium source and it is used as the dopant in this work. Green synthesis is used for the first time to prepare RbCl doped magnesium oxide nanoparticles. Powder XRD, Fourier Transform Infra red (FTIR), EDAX, photoluminescence, SEM, TEM, and antibacterial activity studies were used to evaluate RbCl doped MgO nanoparticles. According to powder XRD measurements, the average particle size was 14.28 nm, which was validated by TEM analysis. The purpose of the FTIR research was to figure out how functional groups are generated in the material. The EDAX studies revealed that the sample contained elements such as Rb, Cl, Mg, and O. Photoluminescence (PL) emission spectrum was recorded and analysed. It is observed that yellow colour emission in PL spectrum is due to presence rubidium as the dopant in MgO nanomaterial. The morphology of the synthesised RbCl doped MgO nanoparticles was confirmed by SEM studies. The zone of inhibition area and antibactierial activity of the prepared sample was also analysed.
