| Abstract: | Effects of the high pressure on the emission spectra of Eu3+-activated L-EuBO3 were considered at room temperature up to 100 kbar. The position of five 0–2 lines in the 5D0→7F2 transition region was determined. The pressure does not have the same effect on all these lines. In four of them, high pressure induced a red shift with different shift rates:+0.0022,+0.0035,+0.0034 and+0.0027 nm kbar?1, respectively, whereas in the last one, high pressure induced a blue shift with shift rate?0.0034 nm kbar?1. Possible reasons for the mentioned pressure effects on the line positions were considered. |
