“…The decomposition of the intermediate Cd(HCOO)2 compound has been described elsewhere by Małecka and co-workers [33]. Cd(HCOO)2 decomposes through the formation of an oxalate anion (C2O4 2− ) which further evolves to the carbonate [27].…”

A systematic study of the thermal decomposition of hybrid perovskites of formula [AH][M(HCOO)3] under inert atmosphere was performed by means of thermogravimetry and simultaneous infrared spectroscopy of the evolved gases. The influence of: (i) the metal ion of the [M(HCOO)3]- framework and (ii) the guest [AH]+ cation, in the composition of the final residue was evaluated. In this work, it has been demonstrated that these materials can be used as precursors of metal or metal-oxide compounds—obtained free of carbon—, and that the composition of the final residue is determined by the standard reduction potential of the metal cation of the framework.

“…The higher direct band gap value with eect of microwave irradiation in the present work is believed to be partly due to the MossBurstein (MB) eect. The blue-shift of the absorption edge has been generally interpreted by the MB eect [22,31]. The higher value of optical band gap arises due to improvement in the crystallinity of CdO during microwave irradiation and this conrms the quantum connement.…”

Cadmium oxide nanostructures were prepared by microwave assisted wet chemical technique at dierent time intervals. Results on structural, optical, and thermal properties of the CdO nanostructures as a function of the microwave irradiation were reported. The X-ray diraction data indicates that the sample showed perfection in the microstructural improvement as a function of microwave irradiation. Surface morphological changes with dierent time of microwave irradiation were recorded by transmission electron microscope and the particle size were found in the ranges from 5 to 30 nm. Chemical composition and thermal stability of the samples were analyzed by energy dispersive X-ray spectrum and thermogravimetric analysis, respectively. The band gaps were shifted towards the blue region due to the MossBurstein eect and it exhibited direct band transitions, which corresponds to optical band gaps of 3.924.20 eV and contrast behavior of optical properties of CdO nanostructure in UV and IR regions were registered. Room temperature photoluminescence spectra revealed that the intensity of luminescent emission tends to decrease with the increase in exposure of microwave irradiation.

“…This change in weight loss with temperature became negligible at 492°C since the transformation of the reminder of the PVP content into carbonaceous products was complete [110], after 492°C, no further weight loss was observed, since the elimination of carbonaceous matter from the sample had occurred between 434 and 492°C [30]. Following thermogravimetric analysis, a change in color from yellow to crystalline white was noted, indicating the formation of binary oxide nanoparticles of high purity [108,[111][112][113].…”
