- We demonstrate efficient and stable dual-wavelength microlasers fabricated by encapsulating different organic dyes into metal–organic framework (MOF) microcrystals. The intermolecular interactions between the organic dyes are suppressed effectively by the spatial confinement effect of the MOF pores, enabling a simultaneously efficient optical gain, and therefore lasing at different wavelengths. The results represent an important step towards a function-oriented laser material design.
