Tin(II) oxide (SnO), as a promising p-type semiconducting oxide, faces challenges due to its oxidation towards the more stable SnO2. In this study, lithium-doped SnO nanostructures were synthesized through a hydrolysis process, showing similar morphology to undoped SnO but with changes in photoluminescence and electrical properties. Theoretical calculations were conducted to support experimental results. The stability of the material under temperature, UV, and VIS-laser irradiation was also investigated to determine its potential applications.
Tin(II) oxide (SnO), as one of the very few p-type semiconducting oxides is becoming a promising key material in different fields of research. However, the oxidation towards the most stable SnO2 commonly hinders its synthesis and applicability. In that sense, insights in the achievement of SnO with controlled dimensions, morphology and doping, as well as in the study of its optoelectronic properties and stability, are required in order to exploit and widen its applicability. In this work, we report on the synthesis of lithium-doped tin(II) oxide (SnO) nanostructures by a hydrolysis process. Li-doped SnO presents similar morphology as undoped SnO, nonetheless Li doping induces changes in the photoluminescence and elec-trical properties. Theoretical calculations have been also carried out, complementary to the experimental results. Moreover, the stability of this material under temperature and UV and VIS-laser irradiation is also studied, aiming to determine the ranges within this material could be exploited.
