【摘要】 <正> In the present note, through partial substituting of O2- by F-, CL- halogen ions, the HPCP (high-pressure cubic phase) of SrB2O4-yXy: Eu2+ (X=F, Cl) has been synthesized at 800℃ and 3.05GPa for the first time. The results show that the QE (luminescence quantum efficience) of HPCP doped by Cl is twice that of HPCP without doping, and 200 times
