Abstract

We report for the first time continuous flow synthesis of NaYF4 : Yb3+, Er3+ upconverting nanocrystals in a capillary-based microfluidic reaction system. Two sequential temperature steps were employed for heating with an initial high temperature (180 °C) step to burst nuclei and a subsequent low temperature (110 °C) step to promote growth of the nanocrystals in order to obtain high-performance nanocrystals. The prepared nanocrystals exhibit green and red emissions under excitation of 974 nm diode laser. Our research opens the door for the synthesis of upconverting nanocrystals in microfluidic systems.
