Eu-complex is one of the most interesting lanthanides organic compounds owing to their high emission efficiency with ultraviolet excitation and sharp emission peak. Combining with an appropriate ligand to form Eu-complexes improves the absorption coefficient of each Eu-ion, and solves the problem of concentration quenching due to the long inter-molecular distance.

Such an interesting characteristics cause the wide range application, such as phosphors of white light-emitting diodes, biosensors and wavelength conversion films for silicon photovoltaic cells. The most serious problem is the decrease in photoluminescence intensity with the UV light irradiation and the thermal stability. Therefore, there has been strong interest in Eu-complex-based organic-inorganic hybrid materials to improve the long-term stability for practical general lighting applications. This book introduces organic-inorganic hybrid emitting materials via a low-temperature sol-gel process. (Imprint: Nova)
