| Abstract: | A high‐stability Eu complex has been achieved by coating with a silica glass via a low temperature sol–gel process using deuterated methanol. A three‐dimensional glass network protects the Eu complex from free oxygen and/or water to change the ligand structure. In addition, the chemical bond of the deuterated Eu complex is more stable than that of the conventional Eu complex. Therefore, we achieved a high‐thermal‐stability Eu complex encapsulated by a sol–gel derived silica glass using deuterated methanol instead of ethanol.  |
