Synthesis of ZrO2:Dy3+ Nanoparticles: Photoluminescent, Photocatalytic, and Electrochemical Sensor Studies

Solution combustion was employed to create a series of ZrO2:Dy3+ (1-11 mol percent) nanoparticles (NPs) using oxalyl dihydrazide (ODH) as the fuel. NPs were subjected calcination at about 700°C. comprised 1 11 mol% Dy3+ characterized by employing X-ray diffraction (XRD), transmission electron microscopic (TEM), UV-visible, and photoelectron spectroscopic (XPS) techniques. The crystallite diameters observed range from 8.1 nm 16.3 nm, exhibiting spherical shape. According BET tests, pore volume determined be 100.129 cm3/g. mean diameter 4.803 Barrett-Joyner-Halenda (BJH) plot. photoluminescence photocatalytic dye degradation properties investigated. acid red 88 (AR88) applied appraise activities under UV irradiation. with 3 exhibited improvised activity due operative departure charge carriers. electrochemical examination NP modified carbon paste electrode in 0.1 N HCl demonstrated considerable redox potential output, evidenced cyclic voltammetric amperometric measurements. sensor studies on potentiality towards sensing highly toxic metals like mercury lead.
