Abstract
Pure ZnO, Eu3+ (3 at.%) doped ZnO, Bi3+ (3 at.%) doped ZnO and Bi3+ (1, 3 at.%) co-doped ZnxO:Eu3+ (3 at.%) have been synthesised through the co-precipitation method at 25 ºC, with ethylene glycol as a capping agent. The crystallite sizes, estimated using the Scherrer equation, ranged from 8-11 nm and were consistent with TEM observations. FTIR analysis confirmed the presence of characteristic Zn–O, O–H and CH2 stretching vibrations associated with ethylene glycol. Furthermore, incorporation of dopants into the ZnO lattice led to a reduction in the optical band gap from 3.07 to 2.85 eV, as determined from Tauc plot analysis, indicating enhanced visible-light absorption. Sensitised Bi3+ (1, 3 at.%) co-doped ZnxO:Eu3+ (3 at.%) samples enhanced its absorption peaks at 464 nm (7F0→5D2) and 394 nm (7F0→5L6) of Eu3+ transition. The photoluminescence emission intensity of Eu3+, observed at 615 nm (5D0→7FJ, where J = 0, 1, 2, 3 and 4), is enhanced through Bi3+ doping than under direct Eu3+ excitation. Bi3+ (3 at.%) co-doped Zn0.94O:Eu3+0.03 has demonstrated promising photocatalytic activity in the degradation of crystal violet dye under UV exposure.
