Abstract

In the preparation of active luminescent glass, trace elements are generally co-doped to improve the properties. To overcome the poor sensitivity of laser-induced breakdown spectroscopy (LIBS) on detecting trace elements in glass, LIBS combined with laser-induced fluorescence was utilized to detect trace Yb, Al and P. A wavelength-tunable laser was used to excited Yb ions, Al atoms, and P atoms. The transition process in laser-induced fluorescence was described. The results showed that the spectral intensities of Yb, Al and P were enhanced by 23, 50 and 8 times, respectively. LIBS sensitivity was demonstrated to be greatly improved by combining laser-induced fluorescence.
