“…The wide peak at 3723 cm -1 was attributed to the Zn-O stretching vibration, while the peak at 716.17 cm -1 was caused by the OH stretching bond vibration. This is because of the vibration of the Pr,Al,Zn-O bonds, which was identified as a peak at a frequency of 716.17 cm -1 over a range of Pr/Al codoped ZnO concentrations [18]. The reason for this is due to the fact that ZnO may be doped with varying amounts of Pr and Al.…”

Using a soft chemical process that involves nitrates and heat annealing, nanoparticles of undoped ZnO and praseodymium, aluminum-codoped ZnO may be produced. XRD, SEM with EDS, and FTIR analysis determine nanocatalyst structures, morphologies, and chemical bonding. PL and UV spectroscopy examines optical characteristics. The peak in the FTIR spectral line at 714 cm-1 in the study indicates M-O stretching in the samples and ZnO's interaction with the Pr and Al matrix. XRD patterns indicated prepared nanoparticles with nanosizes ranging from 40.07 to 38.65 to 36.84 to 38.87 to 39.91 nm. SEM analyzed nanoparticle size, shape, and interaction with the Pr and Al matrix. EDS determined NPs purity. UV-vis spectra of ZnO-Pr/Al nanocomposites showed UV absorption similar to ZnO nanoparticles. Doping ZnO with Pr and Al shrinks the bandgap and slows photogenerated electron-hole pair recombination without changing its crystalline structure.
