The invention relates to a rare earth complex with the light conversion characteristic and a synthesis method thereof. The synthesis method of the rare earth complex is characterized in that bipyridyl ligand with a pinene functional group reacts with rear earth beta-diketone complex to generate the mixed rare earth complex comprising Beta-diketone and 2,2'- bipyridyl derivatives. The rare earth complex provided by the invention has good light absorption properties in the ultraviolet region and can emit visible light, thereby having the light conversion characteristic. The rare earth complex can be used as the critical material of the light conversion film for improving the spectral response characteristics of the solar cell and can be used as the agricultural light conversion film to increase the light energy utilization rate of the crop. The rare earth complex has important application value and wide application prospect in the aspects of analytical chemistry, medicine, life sciences, fluorescent probes and
