It is known that Eu3+ ion shows very strong red fluorescence by forming the complex using a suitable ligand. Here we have prepared the diketone ligand having the amid group and its complex with Eu3+ ion. And we also examined the gelation of the complex. It was found out to form the gel from the complex in the mixture of chloroform and hexane. This gel formation is affected the chemical structure such as a length of the alkyl chain of the ligand. Details are under investigation.
