ABSTRACT:
The invention relates to a method for producing glass, in which an oxide ss is mixed with a reducing agent and a combination of compounds which provide a dopant, donor-acceptor ion pair. This ion pair is selected from the group consisting of trivalent thulium plus trivalent cerium, trivalent bismuth plus trivalent europium, or trivalent bismuth plus trivalent samarium. The resulting mixture is homogenized and heated to about 1100.degree. C. The hot melt is allowed to fall on a ceramic surface and pressed with a second ceramic surface to produce a glass disk. When borax, phosphate, and germanate glasses are used, the glass ingredient is dried overnight at 150.degree. C followed by addition of a quantity of dopant ions, then homogenized, heated, and a disk formed as above.
The glass thus produced is capable of emitting monochromatic radiation in predetermined regions of the spectrum wherein the emitted radiation has an unexpectedly high intensity compared with radiation emitted by singly doped glass.
