Abstract :
To elucidate the role of different subvalent forms of bismuth in observed NIR luminescence we have prepared the phosphate glasses with compositions: 0.8 KMe(PO3)3, 0.2 KBi(PO3)4, where Me = Mg, Ca, Zn. Glasses were fabricated from NH4H2PO4, Bi2O3, ZnO, MgO and CaCO3 starting materials by melting at 1000 οC in air.
