研究了在铝酸盐蓝色荧光粉ＢａＭｇＡｌ１０Ｏ１７Ｅｕ中用Ｃａ代替部分Ｂａ的效果．结果表明，约４～１２ｍｏｌ％的Ｂａ用Ｃａ取代后，抑制了５００ｎｍ以上的长波绿色发射，色坐标Ｙ值减小，而发射峰强度增高，从而改善了这种蓝色荧光粉的性能
The effect of substituting part of Ba with Ca in the aluminate blue phosphor BaMgAl10O17Eu was investigated. The results show that about 4 ~ 12mol% of Ba substituted with Ca inhibits long-wavelength green emission over 500nm, the color coordinate Y value decreases and the emission peak intensity increases, thus improving the performance of this blue phosphor
