Luminescent complexes of Eu(dbm)3phen, β-diketonate Eu(dbm)3phen were loaded on mesoporous silica nanoparticles in a series of concentrations, to study their use as a spectral converter for a multi-crystalline silicon solar cell. This product may be used as a constituent in the preparation of an aqueous micellar anionic surfactant solution to dye anodic porous alumina. Eu(DBM)3Phen is used as an emitter.
