Fluorescence spectra and lifetimes of Sm3+ and Tb3+ were measured in borax, Az203, and borax containing 20, 50, and 80wt% As203. Glasses were formed with all compositions but pure As203 which yielded a crystal of TbAsO4. Fluorescence gradually increased, up to a factor of 3, on adding As203 to borax glass.
