Magnetic and luminescent bifunctional divalent europium nanocrystals (Eu 2+ NCs) are a promising class of novel advanced materials that have various applications in magneto‐optic devices, catalysis, bioimaging, and solar cells. In the past few decades, much work has been carried out to study the synthesis, properties, and applications of Eu 2+ NCs. The aim of this Minireview is to present the progress in preparing Eu 2+ NCs based on the reported research, by describing the advantages and disadvantages of the synthesis methods. The morphologies and size are controlled through adjusting the experimental conditions. Eu 2+ NCs show superior magnetic and luminescence properties simultaneously. Self‐assembly and doping with other ions are important routes to improve their magnetic and luminescence properties. Their applications in magneto‐optic devices are discussed. Some difficulties and challenges in the fabrication of Eu 2+ NCs are discussed, such as water‐soluble Eu 2+ NCs and tunable luminescence in the whole visible region.
