中文摘要	zn2sio4:mn2+, zn2sio4:eu3+ and zn2sio4:mn2+ eu3+ phosphors were prepared by a sol-gel process and their luminescence spectra were investigated. the emission bands from intra-ion transitions of mn2+ and eu3+ samples were studied as a function of pressure. the pressure coefficient of mn2+ emission was found to be -25.3 +/- 0.5 and -28.5 +/- 0.9 mev/gpa for zn2sio4:mn2+ and zn2sio4:mn2+ eu3+, respectively. the eu3+ emission shows only weak pressure dependence. the pressure dependences of the mn2+ and eu3+ emissions in zn2sio4:mn2+ eu3+ are slightly different from that in zn2sio4:mn2+ and zn2sio4:eu3+ samples, which can be attributed to the co-doping of mn2+ and eu3+ ions. the mn2+ emission in the two samples, however, exhibits analogous temperature dependence and similar luminescence lifetimes, indicating no energy transfer from mn2+ to eu3+ occurs.
