GaAs的absorption coefficient curve

<P>那位大虾好心帮忙一下。</P>
<P>这张图的纵轴怎么来读呀？</P>
<P>纵轴的意义是什么？</P><img src="data/attachment/forum/dvbbs/2004-10/20041025131839958.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'data/attachment/forum/dvbbs/2004-10/20041025131839958.gif\');}" onmousewheel="return imgzoom(this);" alt="" />

<P>curve的1，2，3是什么意思，不同的温度吗？</P><P>原来在4um以上也有这么高的吸收系数？才知道</P>

这个是利用荧光光谱测砷化稼量子点得吸收光谱得
