| Abstract: | The thermoluminescence (TL) characteristics of gamma irradiated MgB4O7, MgB4O7:Mn and MgB4O7:Cu phosphors have been studied in the present paper. These phosphors are tried as candidates for PDP panel phosphors. The method of preparation is a standard solid state reaction method. Thermoluminescence studies of gamma irradiated MgB4O7 show a TL peak at 225°C with TL intensity around 65 units. The introduction of 1% dopants like Mn and Cu changes the TL pattern i.e TL peak temperature shifts towards higher side at 233°C. The introduction of Cu creates a hump around 290°C. |
