Organic Holmium(III) Complexes as a Potential Bright Emitter in Thin Films

Abstract

Holmium(III) ions incorporated with an organic ligand generate ∼2 μm optical emission which is characterized by steady and time-resolved photoluminescence. A potential efficient sensitization scheme is demonstrated by empirically calculating the Förster energy transfer rate and modeling the excited state dynamics of the ion. This is demonstrated by taking into account an ideal organic chromophore. The presented work proposes a promising material candidate for the 2 μm emission, which can be fabricated in thin films.
