摘要：
Europium (Eu) doped graphitic carbon nitride has been synthesised using a simple chemical method with two different concentrations of guest material. The as prepared pure and doped samples were characterized by x-ray diffraction and the proper phase formation was confirmed. SEM micrographs showed the microstructure of the samples, whereas the attached energy dispersive x-ray analysis confirmed the successful doping. The optical properties of the samples were studied from UV-visible spectroscopy whereas the different chemical bonds present were confirmed from Fourier transformed infrared spectroscopic analysis. The samples showed good photo-luminescence (PL) property with PL intensity decreases with increasing dopant concentration. It is seen that the sample has potential as the remover of textile dyes like Rhodamine B in the presence of photons in UV range. The removal efficiency increases with increasing doping concentration up to a certain value. The doped sample with 2.65 weight percentage of Eu present, can remove the dye with efficiency more than 90% and almost 100% for contact time 3 and 4 h, respectively. Effort has been given to proposing a mechanism behind the observed photocatalysis performance of the samples.
