Transparent conducting oxides (TCO) offer the uncommon functional combination of being both transparent and electrically conductive. For this reason, this study is concerned with the preparation of the triple heterojunction consisting of magnesium oxide, alumina, and ITO using a pulsed laser deposition method with a laser intensity of 3 J. Alumina bulk pellets in propanol were irradiated (Nd:YAG) at a wavelength of 1064 nm. Laser ablation was performed at a laser intensity of 3 J and deposited on ITO, which was then left to dry for 24 hours. The same method was used to attain magnesium nanoparticles, which were spin-coated on the previous sample and dried in a 500 °C oven for 4 hours. Then the properties of nanoparticles were investigated using X-ray diffraction, UV spectroscopy, and scanning electron microscopy (SEM). The results were obtained by UV and XRD analyses. From SEM images, the average size of the synthesized nanoparticles was determined to be about 25–35 nm. Aluminum oxide, MgO, and ITO are 1-D nanostructured semiconductors that function as transparent conducting oxide thin film while also increasing absorption in the visible spectrum. ITO is identified as an appropriate electrode material for infrared photoelectric devices.

Los óxidos conductores transparentes (TCO, por sus siglas en inglés) poseen la combinación funcional poco frecuente de ser transparentes y conductores de la electricidad. Por este motivo, este estudio se centra en la preparación de la heterounión triple formada por óxido de magnesio, alúmina e ITO utilizando un método de deposición por láser pulsado con una intensidad de láser de 3 J. Se irradiaron gránulos de alúmina en propanol (Nd:YAG) a una longitud de onda de 1064 nm. La ablación por láser se realizó a una intensidad de 3 J y se depositó sobre ITO, que se dejó secar durante 24 horas. Se utilizó el mismo método para obtener nanopartículas de magnesio, que se recubrieron por rotación sobre la muestra anterior y se secaron en un horno a 500 °C durante 4 horas. Posteriormente, se investigaron las propiedades de las nanopartículas mediante difracción de rayos X, espectroscopia UV y microscopia electrónica de barrido (SEM, por sus siglas en inglés). Los resultados se obtuvieron mediante análisis UV y difracción de rayos X. A partir de las imágenes de SEM, se determinó que el tamaño medio de las nanopartículas sintetizadas era de unos 25-35 nm. El óxido de aluminio, el MgO y el ITO son semiconductores 1-D nanoestructurados que funcionan como películas finas de óxido conductor transparentes al tiempo que aumentan la absorción en el espectro visible. El ITO se identifica como un material de electrodo apropiado
para dispositivos fotoeléctricos infrarrojos.
