摘　　要：以青粉用量和半波宽为变量,光通量、显色指数、色温等光色参数为评价指标,采用计算机模拟技术对青粉调控的发光塑料光谱进行了研究。结果表明:随着青粉用量的增加,光通量降低,最高降幅达54%,显色指数则先升高后降低,在青粉用量为7%(w)时具有最优值(94.33);未掺杂青粉时,蓝光强度非常大,色温为8913 K,青粉用量为11%(w)时,色温为3571 K,色坐标则表现出线性关系;光通量随着半波宽的变化幅度较小,半波宽为5.0 nm时,光通量为33.58 lm,半波宽增加到15.0 nm时,光通量为34.15 lm,增幅仅为2%,色温变化最大值仅为247 K,显色指数在半波宽12.5 nm时具有最优值(94.33);青粉用量为7%(w),半波宽为12.5 nm时,显色指数为94.33,色温为4078K,色坐标为(0.3865,0.3839)。The spectrum of luminescent plastics regulated by green powder was studied by computer simulation technology with green powder doping and half wave width as variables,photochromic parameters including luminous flux,rendering index,and color temperature as evaluation indicators.The results show that the luminous flux falls with a maximum decrease of 54%as the mass fraction of green powder increases.The rendering index first increases and then decreases and reaches the optimal value of 94.33 when the mass fraction of green powder is 7%.The color temperature decreases from 8913 K which is a very high blue light intensity without doping,to 3571 K when the mass fraction of green powder is 11%.The color coordinates show a linear relationship.The change in luminous flux with half wave width is relatively small,from 33.58 lm at 5 nm to 34.15 lm at 15 nm,with an increase of only 2%.The maximum change in color temperature is only 247 K,indicating an optimal value of rendering index of 94.33 at half wave width of 12.5 nm.The rendering index is 94.33,the color temperature is 4078 K,and color coordinates is(0.3865,0.3839)for luminescent plastics when the mass fraction of green powder is 7%and the half wave width is 12.5 nm.
