Successive preparation of decorated zinc oxide organic sot by pulsed laser ablation and their luminescence characteristics
Nano-ZnO organic sols which were modified in situ were successively produced through focused pulsed laser ablation of ZnO target in interface of solid and flowing liquid which contained modification agents or polymer. It is found that the ZnO ethanol sot decorated by Q (8-hydroxylquinoline) radiates intense green light under ultraviolet radiation and has a broad emission band centered at 555 nm in the emission fluorescence spectrum. The influence of factors including different modification agents and their added methods, laser fluence, aging time after preparation, compositiens of flowing liquid and their velocity on luminescence characteristics ofnano-ZnO organic sot was characterized by TEM, UV-vis and fluorescence spectrum.
