摘要
Lanthanide-doped nanoparticles,which contain lanthanide ions doped in an inorganic host,can generate wide wavelength range emissions corresponding to inner shell 4 f-4 f transitions of lanthanide ions[1–3].Unfortunately,lanthanide 4 f transitions have a narrow absorption band and small absorption cross-section(10-20 cm2)when compared with organic dye molecules(around10-17–10-16 cm2),posing a critical brightness performance limit of lanthanide ions[4,5].
