【 摘 要 】

In the search for new sources of light and gain media for lasers, lanthanide fluoride powders and rare earth tri-iodide salts in vapor phase have been studied spectroscopically by photopumping in the ultraviolet. Knowing the spectral response of these molecules with respect to incident light and understanding the energy level structure entailed would be useful to establish their suitability for lighting or lasing. This thesis describes the spectroscopic experiments performed, reports the measured data and analyzes them.
