Synthesis of Ga-riched zinc gallate nanowires by reactive evaporation and the cathodoluminescence properties of individual nanowires
A facile Au-catalytic reactive evaporation method was developed to synthesize cubic zinc gallate (ZnGa 2O 4) nanowires through the reaction of Ga 2O 3 film and ZnO vapor at high temperature. The ZnGa 2O 4 nanowires are well crystalline and the length is up to tens of micrometers. The growth process...

Summary: | A facile Au-catalytic reactive evaporation method was developed to synthesize cubic zinc gallate (ZnGa
2O
4) nanowires through the reaction of Ga
2O
3 film and ZnO vapor at high temperature. The ZnGa
2O
4 nanowires are well crystalline and the length is up to tens of micrometers. The growth process follows typical vapor–liquid–solid (VLS) mechanism. All the cathodoluminescence (CL) spectra of individual nanowires reveal a strong, broad and asymmetric blue emission band centered at
ca. 460
nm. It is thought that the excess Ga
3+ is the main reason for the unusual blue emission properties. |
