A ratiometric luminescence sensing method is developed and makes the chemically stable Eu metal-organic framework to be the first bifunctional chemical sensor for Cd2+ and F- ions with naked-eye observation in the field of sensing applications utilizing luminescent Ln-MOFs. This is the first example of luminescent colorimetric sensor caused by the direct dual emissions of a single Ln-MOF. A recyclable vapoluminescent sensor for HCl and NH3 by the naked eye has also been realized.
