Solid-state lanthanide luminescent materials have the combined advantages of typical lanthanide luminescence and photophysical stability. In these materials, lanthanide ions are trapped into the rigid crystal host lattice, avoiding adverse quenching by environmental oscillators. Two types of luminescence modes, downconversion and upconversion, are known for lanthanide luminescence. Upconversion relates to a nonlinear optical process where two or more near-infrared (NIR) photons are absorbed sequentially to several real intermediate energy states and luminescence is emitted with a... [Pg.389]
