Disclosed is a method for controlled growth of three-dimensional nanocrystals, and the nanocrystals resulting therefrom. In one form, there is provided a method of controlled nanocrystal growth, comprising the steps of : partial dissolution of a core part of a nanocrystal; and epitaxial growth of new nanocrystal onto a selective surface of the nanocrystal. In examples, the nanocrystal is a hybrid nanocrystal, and/or is or includes an alkaline rare-earth fluoride (AREF4) nanocrystal(s). A surfactant can be used to control the nanocrystal growth.
