Hexagonal phase ytterbium and erbium co-doped sodium yttrium fluoride (NaYF4:Yb,Er) nanocrystals have been demonstrated as the most promising IR-to-visible up-converting materials displaying best luminescence properties among nanophosphors. There is yet an efficient and easy way of synthesizing hexa...
