EFFECTIVE MgO /ALUMINA / ITO NANO HETEROSTRUCTURE AS SMART MATERIAL FOR LIGHT-EMITTING DIODE

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