In addition, the recombination for large numbers of charge carriers would occur in the volume or on the surface of TiO_2. Therefore, the extension of the photoactive wavelength region of TiO_2 into the visible region and improvement of quantum efficiency are desirable for popularizing more TiO_2 photocatalyst, especially under solar light for industrial areas or poor interior lighting illumination in living spaces.

但纳米TiO_2具有较宽的禁带宽度，只能吸收太阳光中5%左右的紫外线，而太阳光中近45%的可见光在处理污染物中却得不到有效利用，因此太阳能的利用率较低，这就限制了其实际使用范围；另外，TiO_2半导体载流子的复合率较高，因此量子效率较低。

In the study of UV absorbing test, polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10) shows better ability to absorb UV and shows wider range of absorbing UVB than control group, octyl salicylate. With respect to octyl salicylate, octyl salicylate can abosorb the highest wavelength up to 306 nm under UVB (wavelength ranges 280 nm ~320 nm), and the ε is 4.03 × 103 ㎝-1M-1. However, the ε of polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10) under 306 nm range 4.14 × 103 ~ 11.45 × 103㎝-1M-1. It is reasonable that the compounds in this study can not only absorb the individual wavelength amoung the wavelenght of UVB, but also absorb wider range of wavelength.

在紫外线可见光吸收测试结果显示，相较於对照组水杨酸辛酯在UVB波长(280 ~ 320 nm)范围最大吸收波长为306 nm，其莫耳吸收系数为4.03 × 103 ㎝-1M-1，而多羟基取代之N-色洛冬宁苯甲醯胺衍生物（化合物1 ~ 10）在306 nm的莫耳吸收系数介於4.14 × 103 ~ 11.45 × 103㎝-1M-1，其吸收紫外线的效果皆优於对照组水杨酸辛酯，且其在UVB波长的范围吸收波长的光谱也较宽广，可知每个化合物并非只是对UVB波长范围内的单一波长有吸收度，而是对UVB波长范围具有较宽广的光谱吸收。
