چکیده
The novel red-emitting BaBi2-xEuxB4O10 (x = 0.05, 0.1, 0.2, 0.25, 0.3, 0.4, 0.5, 0.6) phosphors were obtained by a crystallization from glass. Distribution of the Eu3+ ions over cation sites refined for x 0.3 and 0.4 single-crystal X-ray diffraction data. Emission excitation spectra Eu3+-doped BaBi2B4O10 investigated first time, where it was shown that characteristic lines are attributed to intraconfigurational 4f-4f transitions. optimal concentration is after which luminescence intensity decreases. CIE chromaticity coordinates BaBi2B4O10:Eu3+ 0.4) phosphor (0.65, 0.35) close NTSC standard values (0.67, 0.33) commercial red phosphor. results show promising candidates solid state lighting application.

متن کاملRadioluminescence of red-emitting Eu-doped phosphors for fiberoptic dosimetry.
Fiberoptic dosimetry (FOD) technique has become an attractive method for real-time dosimetry. Al(2)O(3):Cis one of the most used radioluminescence materials for FOD due to its high efficiency but it presents the drawback of emitting in the spectral region, where spurious luminescence is also important. Optical filtering is the simplest technique to remove spurious luminescence, but is useful wh...
