Surface Property and Enhacement Mechanism of Blue-light Emission of Ion Injecting Si3N4 Quantum Dots
We examined the surface property of nanometer Si3N4 quantum dots, before and after N+ ion injection. XPS measurement revealed that there were more oxygen existing on the surface comparing to that in the bluk. After ion injection, there were more oxygen existing on the suface, furthermore adsobing oxygen converted to binding oxygen. The exciton effect in the interfacial layer played role in enhancing blue-light emission.
