ZnO

It is Er doped ZnO compound. It was produced by sol-gel method. ZnO is a wide-bandgap semiconductor. As can be seen from the figure, it has hexagonal structure. ZnO has several favorable properties, including good transparency, high electron mobility, wide bandgap strong room-temperature luminescence that used in various applications. And the properties that mentioned above can be improved by adding some kind of dopings Because of these reasons we have tried to produced Er doped ZnO in nanoscale.
