<p>The invention relates to a phosphor, a luminescent mixture and a luminescent material, characterized in that the phosphor, the mixture or the luminescent material comprises blue afterglow luminescence material A and yellow luminescence material B, wherein the blue afterglow luminescence material A is at least one of Sr 4 Al 14 O 25 :Eu 2 , Dy 3+ ; CaS:Bi 3+ ,Na + ; CaS:Cu + ,Na + or CaSrS:Bi 3+ , the yellow luminescence material B is at least one of Y 2 O 3 €¢Al 2 O 3 €¢SiO 2 : Ce€¢B€¢Na€¢P; Tb 3 Al 5 O 12 :Ce; Y 2 O 2 S:Mg,Ti; Sr 3 SiO 5 :Eu 2+ ,Dy 3+ ; CaS:Sm 3+ ; YAG:Ce or TAG: Ce, a weight ratio between the blue afterglow luminescence material A and the yellow luminescence material B is 10~70wt%: 30~90wt%, and under directly being supplied with an alternating current without converting alternating current to direct current, the phosphor, the mixture or the luminescent material can emit low-flickering light in combination with LED chips.</p> |
