Abstract :
This letter reports ZnO nanonanocrystals with tunable visible fluorescent emission which utilizes optically stimulated luminescence (OSL). ZnO nanonanocrystals deposited on glass substrates, and the blue-shifted two narrow photoluminescence peaks at the violet band and green band have been observed for the first time. Such promising multiwavelength tunable nanocrystals can be easily fabricated and are very attractive for a variety of applications such as synchronous fluorescent sensing, DNA sequencing, bioprocess monitoring, etc.
