Abstract

This study reported the influence of La10Si6O27:Eu3+ nanophosphor prepared by solution combustion method by using oxalyl dihydrazidecas fuel on the electrochemical performance in HCl used as an electrolyte. The structural morphology of the nanoparticles was characterized by PXRD, it confirms pure hexagonal oxyapatite phase with the crystallite size averaging between 20-30 nm. To examine the electrochemical behaviour of the nanophosphor in an acidic medium, both electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) techniques were utilized. For the electrochemical analysis used in this study, a modified carbon paste electrode (CPE) with the nanophosphor was utilized as the working electrode, which is an excellent sense of the paracetamol and sildenafil citrate (viagra). Further, the synthesized La10Si6O27:Eu3+ nanophosphor exhibited improved photocatalytic mobility (PCM) and enhanced photostability when exposed to UV light during the decomposition process of direct green dye. These findings suggest that the developed material holds great promise as a potential sensor and photocatalyst.
