The absorption and luminescence spectra of silica fibres doped with chromium and various dopants are studied. Fibres doped with aluminium and gallium exhibit a broad (300 nm) luminescence band of Cr{sup 4+} ions at 1100 nm at room temperature. The quantum yield of luminescence is estimated to be 10{sup -4}-10{sup -5}. (optical fibres)
