Solid-state materials with tunable light emission characteristics offer an attractive prospect. Unique luminescence features of trivalent lanthanide (LnIII) ions?sharp characteristic emission in the visible and near-infrared (NIR) spectral regions, exceptional color purity, long luminescence lifetimes, high quantum yield and large Stokes shifts?afford them as promising white-light source materials. Our research contributes to the development of the Ln- complex-based solid-state white-light emitters with particular emphasis on different design strategies and photoluminescence features to augment the foundations of factual knowledge further. The approaches adopted in the lanthanide coordination complexes?logical codoping of LnIII in various compositions, lanthanide encapsulation in MOF pores, infinite coordination particles, and lanthanide incorporated composites?to attain tunable white-light emission.
