为了开发适合等离子体显示板（PDP）的绿色荧光粉，采用高温固相反应法制备了Ca_（5 - 2）xTb_xNa_x（PO_4）（3）F（x=0.20，0.35，0.50，0.65，0.80和0.95）样品。研究了真空紫外（VUV，波长λ < 200 nm and the energy E>50，000 cm（-1））维斯光谱特性和衰减特性。由于x=0.95的磷光体Ca 5 - 2xTb xNax（PO 4）（3）F在真空紫外（VUV）范围内显示出宽而强的吸收，在147/172 nm激发下显示出更高强度的发射，并且与商业绿色PDP磷光体Zn 2SiO 4/Mn 2+相比具有更短的衰减时间（τ类似于2.19 ms），因此它被认为是PDP中有前景的绿色磷光体。(c)2007年，电化学研究。
In order to develop a suitable green phosphor for plasma display panels (PDPs), samples Ca5-2xTbxNax(PO4)(3)F for x=0.20, 0.35, 0.50, 0.65, 0.80, and 0.95 were prepared by a solid-state reaction technique at high temperature. The vacuum ultraviolet (VUV, wavelength lambda < 200 nm and the energy E>50,000 cm(-1))-vis spectroscopic properties and decay characteristic were investigated. Because the phosphor Ca5-2xTbxNax(PO4)(3)F for x=0.95 shows broad and strong absorption in the vacuum ultraviolet (VUV) range, exhibits higher intensive emission under 147/172 nm excitation, and has a shorter decay time (tau similar to 2.19 ms) in comparison with the commercial green PDP phosphor Zn2SiO4/Mn2+, it is considered to be a promising green phosphor in PDPs.
