Abstract

Blue-color stimulated emission with low threshold power is observed from In- and Zn-MOFs, which feature a highly fluorescent chromophore densely packed and rigidly linked to the metal-ion centers in the solid state. The density-of-states and transition dipole moments are calculated and the stimulated emission phenomenon is correlated with these properties.

Keywords: blue emission; hybrid materials; nonlinear optics; stimulated emission; two-photon excited fluorescence.
