Abstract: The new borate phosphors Na 2 Y 2 B 2 O 7 :Eu 3+ and YCa 3 (AlO) 3 (BO 3 ) 4 :Eu 3+ were synthesized and their luminescence properties were investigated under vacuum ultraviolet (VUV) excitation. Under VUV excitation, strong orange emission of 5 D 0 → 7 F 1 at 592 nm was observed in the emission spectrum of Na 2 Y 2 B 2 O 7 :Eu 3+ and the best concentration for Eu 3+ was 10%. While strong red emission of 5 D 0 → 7 F 2 transitions at 621 nm was observed for YCa 3 (AlO) 3 (BO 3 ) 4 :Eu 3+ and the most intense e…
