Abstract

This work has studied the effect of co-doping Er

enhanced BaSi

∶Eu

luminescence

mainly focusing on the internal difference and possible mechanism. The Er

co-doped crystal structure was demonstrated through XRD test

and the purity of the sample and the difference in growth were confirmed by analysis. In order to find out the sources of differences

the emission spectra of doped ions with different valence states have been monitored

and the emission spectra of the changes with the content of Er

have been compared. The internal physical mechanism of co-doping Er

enhanced luminescence is seen from the change of the luminescence. The internal physical mechanism of the co-doping Er

enhanced luminescence is to control the crystal texture and adjust the valence state. For practical applications in the future

a temperature characteristic test was carried out to show the emission spectrum changes under temperature variation. This research provides new ideas for the work of regulating the luminous intensity and improving quantum efficiency.
