A solvent evaporation induced assembly method is applied to assemble NaREF 4 nanocrystals into 2-or 3-dimensional structures. The assembly behavior can be tuned with various starting concentration of the nanocrystals and the evaporation rate. This method is also explored to the hybrid, chain or ring like assemblies by using different nanocrystals or solvents.
