在荧光灯方面,对于作为三基色的各荧光粉的合成条件等进行了较为详细的探种讨,而且力求提高其性能。在CRT方面,对于作为现代显示用的许多荧光粉应具备的特性,重新进行了研究。关于发蓝光的(Ba,Ca,Mg)_(10) (PO_4)_6:Eu~(2+),改变Ba、Ca比就能使发光峰值移动。报导了在5000K的白光灯中使用峰值为442nm的粉,可获得3400lm/40W, In terms of fluorescent lamps, the synthesis conditions of phosphors as the three primary colors have been investigated in more detail, and their performance has been enhanced. On the CRT side, the properties of many phosphors used as modern displays have been re-examined. With regard to the blue-emitting (Ba, Ca, Mg) _ (10) (PO_4) _6: Eu ~ (2+), the emission peak can be shifted by changing the Ba and Ca ratios. Reported the use of a peak of 442 nm powder in a 5000K white light to achieve 3400 lm / 40 W,
