Their thermaldecomposition process has been analyzed in situ by thermogravimetric analysis (TGA), differential scan-ning calorimetry (DSC) and evolved gas analysis (EGA), whereas the solid product has been analysedex-situ by X-ray diffraction (XRD) and infrared spectroscopy (IR). Although, except for the APh ink, crys-talline ZnO is already obtained at 300◦C, the films contain an organic residue that evolves at highertemperature in the form of a large variety of nitrogen-containing cyclic compounds. The results indicatethat APr can be a better stabilizing agent than ethanolamine (EA). It gives larger ZnO crystal sizes withsimilar carbon content. However, a common drawback of all the amino stabilizers (EA included) is thatnitrogen atoms have not been completely removed from the ZnO film at the highest temperature of ourexperiments (600◦C).6 p.application/pdfengcc-by-nc-nd (c) Elsevier B.V., 2016http://creativecommons.org/licenses/by-nc-nd/3.0/esDescomposició (Química)Propietats tèrmiquesÒxids metàl·licsEspectroscòpia infrarojaDifracció de raigs XDecomposition (Chemistry)Thermal propertiesMetallic oxidesInfrared spectroscopyX-rays diffractioninfo:eu-repo/semantics/article6607902019-02-15info:eu-repo/semantics/openAccess
