摘　　要：The fluorescence emission and X-ray diffraction of magenesium 8-hydroxyquinoline complex(Mgq2) have been measured at high pressure up to 14 GPa.It has been found that pressure can influence the emission dramatically.At relative lower pressure(less than 2.5GPa) the fluorescence of Mgq2 changes slightly,but the emission drops quickly with increase of the pressure when the pressure gets higher than 2.5GPa.The results of in situ energy dispersive X-ray diffraction at high pressure with synchrotron radiation indicate that there is a phase transition at about 2.5-3GPa for Mgq2 crystal.2001 Elsevier Science B.V.All rights reserved.
