New Nanocrystals Study Results Reported from Jilin University

February 28, 2014

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Nanocrystals have been published. According to news reporting from Changchun, People's Republic of China, by NewsRx journalists, research stated, "Mild molten salt synthesis (MSS) method was utilized to synthesize rare earth fluorides nanocrystals with favorable fluorescence efficiency. LaF3 nanocrystals were achieved through this modified MSS method by only using La(NO3)(3).6H(2)O and NH4HF2 as starting materials."

The news correspondents obtained a quote from the research from Jilin University, "NH4HF2 is difunctionality as both fluorine source and the flux. The effects of reaction time and temperature to the synthesis of LaF3 nanocrystals were discussed in detail. The fluorescence of LaF3 nanocrystals was detected with excitation wavelength of 360 nm, the results showed a broad band emission centered at 475 nm. The photoluminescence properties of pure LaF3 nanocrystals and Eu3+ doped samples were also investigated. In our work, white light emission was achieved in single element (Eu3+) doped LaF3 nanocrystals by adjusting the concentration of Eu3+ ions."

According to the news reporters, the research concluded: "This would be the combination of broad emission of LaF3 nanocrystals and sharp line emission of Eu3+ in the LaF3:Eu3+ nanocrystals."
