    Abstract: There are described luminescent glasses having the following compositions (a) 0 to 80 mole % alkali metal oxide (sodium oxide, potassium oxide, lithium oxide), individually or several together, 0 to 30 mole % alkaline earth metal oxide (magnesium oxide, calcium oxide, strontium oxide, barium oxide), individually or several together, and at least 2 mole % of alkali metal oxide and/or alkaline earth metal oxide must be present (b) 7 to 90 mole % silica 1 to 50 mole % boron oxide (B2O3) 1 to 30 mole % aluminum oxide (c) 0.1 to 5 mole % lead oxide (PbO) 0.1 to 10 mole % vandium pentoxide (V2O5). The glasses have white, yellow, or blue luminescence, depending on the PbO and V2O5 content, at excitation with a wave length of 254 nm.
