| 英文摘要 | monodisperse beta-nayf4:ln(3+) (ln = eu, tb, yb/er, or yb/tm) nanocrystals with multiform novel morphologies have been synthesized for the first time by a novel two-step ion-exchange route expressed as y-2(oh)(5)no3 center dot nh(2)o (lyh) -> y(oh)(x)f3-x -> beta-nayf4. in step i (lyh -> y(oh)(x)f3-x), the y(oh)(x)f3-x is fabricated using a one-pot method from the starting point of a unit layer at low temperature through a novel style of ion-exchange from lyh based on the special crystal structural similarity between the lyh unit layer and the y(oh)(x)f3-x {0001} plane. of particular interest is that the ion-exchange process in step i can be completed within the initial few minutes, and the unique two-dimensional layered structure of lyh greatly favors the ion-exchange reaction by exfoliating into atomically thick monolayers. meanwhile, the identical structural framework between y(oh)(x)f3- x and beta-nayf4 ensures the in situ ion-exchange reaction in step ii. the composition of the intermediate precursor y(oh)(x)f3-x can be tuned in a wide range, which gives the synthetic parameters high maneuverability and greatly simplifies the experimental variables. in addition, the luminescence properties showed that the as-prepared beta-nayf4:ln(3+) nanocrystals exhibited strong characteristic multicolor emissions through upconversion and downconversion. |
