Abstract

A microfluidic reactor heated by microwave (MW) irradiation was utilized for the first time to prepare LaF₃/LaPO₄ : Ce,Tb nanocrystals (NCs) using ethylene glycol (EG) as solvent. Redispersible and water-soluble LaF₃ nanoparticles with a mean diameter of 4.5 nm, and LaPO₄ nanorods with a length of 60–70 nm and diameter of 10–15 nm were simply obtained. Dielectric heating by the irradiation and the special MW effect combined with the microfluidic reactor accelerate the nucleation stage and promote the growth stage of NCs, which results in improved luminescent properties and yields of products.
