Nanomaterials are materials that have developed rapidly in recent years and may play a significant role in the 21st century. Nanoparticles have characteristics not available in conventional materials in terms of magnetism, light, electricity, sensitivity, etc. The preparation of metal atom clusters with controlled size and shape is It has always been a challenging field in nanomaterials science. Using discrete and delicate dendrimers as templates can control the size, stability and solubility of nanoparticles, so dendrimers are especially suitable for metal nanoparticles. main body.

The dendrimer is of suitable size and has internal cavities and surface end groups, making it a template for synthesizing metal nanoparticles. Using dendrimers as a template and sodium borohydride as a reducing agent to react with europium, europium nanoparticles with an average particle size of about 4.7 nm ± 0.5 nm and uniform distribution can be obtained.

The algebraic number of dendrimers determines their ability to act as both a template and a stabilizer during the reaction. Higher dendritic dendrimers are more suitable as template and stabilizer.
