Abstract : The patent application concerns glasses such as borate glass, phosphate glass, calibo glass and germanate glass containing predetermined quantities of certain components adapted to result in the emission of radiation in the desired spectral range, and at a desired predetermined intensification. Glasses of the invention contain either a combination of thulium and cerium or a combination of bismuth with either europium or with samarium. The rare earths dopant ions, upon excitation of various types of radiation, emit radiation of a predetermined wavelength or of more than one predetermined wavelength many times the intensity of the exciting radiation.
