I know that atoms absorb photons, which promotes electrons to higher energy levels, then. Then upon de-excitation a photon is released. Is it true that the lines for absorption and emission spectrums are the same i.e. the same wavelengths are both absorbed and emitted?

I believe this is true, but then how does this explain fluorescent minerals? You shine a UV light on them of some wavelength, then they will emit a characteristic color, such as red, which is not the same wavelength as the UV light. How does this work?

Do atoms emit and absorb photons at the same wavelengths?
