Abstract
The main objective of this investigation is to improve the photoluminescent performance of existing phosphors by adding a new co‐dopant. The candidate co‐dopants adopted in the present investigation are confined to substituents for the Zn site. In this context, the co‐doping effect of Mg and/or Cr upon emission intensity and decay time was studied in the present investigation. The co‐dopants incorporated into the phosphors are believed to alter the internal energy state so that the change in emission intensity and decay time could be expected. Both Mg and Cr have a favorable influence on photoluminescent properties, in particular, Mg enhances the intensity of manganese green emission and Cr shortens the decay time. The enhancement in emission intensity of , Mg phosphors was interpreted by taking into account the result from the DV‐Xα embedded cluster calculation. On the other hand, the energy transfer between Mn and Cr ions was found to be responsible for the shortening of decay time in phosphors. © 1999 The Electrochemical Society.
