Multifunctional La10Si6O27:Tb3+ tailored material for photoluminescence, photocatalysis and electrochemical sensing applications

La10Si6O27: Tb3+ (1-9 mol%) materials were synthesized by the combustion method and characterized by PXRD, PL, CV, EIS and UV-Vis spectroscopy to explore its photoluminescent, electrochemical and photocatalytic properties. These materials exhibited crystalline and single phases even after doping Tb3+ ions into the lattice of La10Si6O27. PL analysis confirms a tunable and maximum emission for optimized concentration. Electrochemical analysis shows La10Si6O27:Tb3+ (9 mol%) electrode as a paracetamol and penegra sensing material. The average specific capacitance of this electrode at 10 mVs(-1) was found to be 262 Fg(-1). A Photocatalysis study was performed using La10Si6O27:Tb3+ (5 mol%) material as a photocatalyst for the degradation of direct green dyes. Therefore, La10Si6O27:Tb3+ can be used as a multifunctional material for photoluminescence, photocatalysis, and electrochemical sensing applications.
