The second experiment is to fabricate white light LED from red and green phosphors pumped by blue light LED. The blue light LED we used in our experiment has the wavelength range between 450 and 452.5 nm, and the chip size is 17 mil *14 mil. There are two kinds white light LED we fabricated in the experiment. There are three blue light LED chips bonded in single package of both kinds package. The different of the both packages is mixed phosphor of encapsulation. One of the experimental devices was encapsulated YAG phosphor mixed silicone to fabricate white light. The other is red and green phosphor mixed encapsulation. The compared and focused parameter was luminous efficiency. YAG phosphor pumped white light has the luminous efficiency 72 lm/W, CRI 70, CIE(0.32, 0.33), CCT 5622°K at the operating current 60mA. On another hand, red and green phosphor pumped white light LED has the luminous efficiency 55 lm/W, CRI 90, CIE(0.31, 0.32), CCT 6479°K at the operating current 60mA. We fabricated the red and green phosphor pumped white light LED, and proved that it could has much higher CRI under similar compared conditions, CIE xy and CCT.

第二个实验是使用蓝光LED晶粒来制作白光元件，蓝光LED晶粒波段范围在450 ~ 452.5 nm，晶粒大小为17*14 mil，以三颗蓝光LED晶粒搭配YAG萤光粉(黄绿光 540 nm)制成白光元件，再以另外三颗蓝光LED晶粒搭配红色萤光粉(613 nm)混合绿色萤光粉(519 nm)制成的白光元件进行发光效率比较；搭配YAG萤光粉的白光元件在注入60 mA的电流时所量测到最大的发光效率是在72 lm/W，演色性数值大约为70，CIE色度座标为(0.32， 0.33)，色温是在5622 °K；而搭配红色萤光粉混合绿色萤光粉的白光元件在注入60 mA的电流时，最大的发光效率在55 lm/W，演色性数值大约为90，CIE色度座标为(0.31， 0.32)，色温在6479 °K；证明了蓝光LED晶粒搭配红色萤光粉混合绿色萤光的白光元件演色性指数可以高达90 以上的结果。

HPLC method of determination of CCU has been developed for the kinetic study. The kinetics of photodecomposition of CCU in various carrier gases have been studied. The photoreaction of CCU in nitrogen and air is of the first order, while in oxygen is closer to that of the second order. The rate constants in nitrogen, air and oxygen are 0.00703/h, 0.0109/hand 0.00445 , and the half-livies are 98. 6, 63. 6 and 62. 7hour respectively.

采用以甲醇一水为流动相的反相HPLC作为分析手段，对灭幼脲在不同载气中的光解动力学作了研究，结果表明，灭幼脲在氮气和空气中的光解反应符合一级动力学形式，而在氧气中的光解则更接近于二级反应形式；在三种气氛中的反应速度常数分别为0.00703h〓，0.00109h〓和0.00445h〓〓，半衰期相应为98.6、63.6及62.7h。
