Compared with co-doped glass, the energy transition pathways were increased, where two additional green emission peaks at 486\u2009nm and 500\u2009nm were observed. As a result, the bandwidth was broadened from 49 to 97\u2009nm. The noncrystalline properties, absorption peaks, and broadband mechanism in interlayer-doped samples were discussed in detail.
