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。

The results were as follows:(1) The spectral sensitivity response at 14 monochromatic light selected through 340nm to 605nm occurred in curve with multiple peaks, the primary peak in 340nm (ultra-violet) is the highest response rate of phototaxis (21%), the secondary in 524nm, and the rest in 400-440nm and 483nm in order;(2) The response rate of phototaxis is increasing as the relative intensity of light, it is showed as curves with inverse "L" shape in white light and the monochromatic light of 483nm, as an upward ladder at 524nm and a near straight line at 340nm. However, the response rate could be detected at the lowest intensity and not arrived to the summit at the strongest yet;(3) The effect of sex to response to the spectral sensitivity and intensity is not significant;(4) There was not significant photophobism response to light for the ladybird, the behavior probably derived from phototaxis or partly due to random movements. It can be concluded that both the spectrum and intensity of light stimulus gave rise to the phototaxis of P.

结果显示：（1）在340~605nm波谱内其光谱趋光行为反应为多峰型，峰间主次不明显，紫外340nm处峰最高，趋光反应率达21%，其它各峰依大小次序分别位于绿光524nm、蓝光400~440nm和483nm处；（2）随光强增强其趋光反应率增大，白光和483nm刺激时其光强趋光行为反应呈一倒"L"型式样，524nm时呈一阶梯型，340nm时为一较平直的线型；光强最弱时仍均有一定趋光率，最强时均未出现高端平台；（3）性别对其光谱和光强度行为反应均有一定影响，但影响不大；（4）龟纹瓢虫无明显的避光反应，其避光行为可能是趋光行为衍生或其随机活动造成。

Plate and λ/2 plate were placed inside the Nd∶YVO4KTP green laser cavity with angle 90°between their fast axis.The composite plate composed of HWP,QWP and KTP has the function of QWP.The composite plate with Nd∶YVO4 can effectively suppress the coupling of polarized modes,and multi-longitudinal-mode lownoise green laser was obtained.Since the composite plate counteracted the phase shift induced by temperature sensitivity of quartz plate,the green laser operated with lownoise reliability in different output power and different operation temperature.The threelongitudinalmode, the noise of less than 0.5% and output power stability of less then 1% for 12 hour are obtained in the green laser.

If left the first figure below, the red, green, and blue light have magenta ink transmissional, green light be absorbed, the rest of the red and blue light the blue light was the last yellow ink absorption, is not absorbed hongguang reflected, i.e. magenta inks and ink overlay after yellow to red.

如左第一幅图所示，红、绿、蓝光透射过品红墨后，绿光被吸收，剩下的红、蓝光其中的蓝光又被黄墨吸收，最后未被吸收的红光反射出来，即品红墨和黄墨重叠后表现为红色。

We gained 3.3W green laser when we pumped the system at 25W power while the temperature of Nd: YVO4 was controlled at 22℃, LBO was at 18℃, the efficiency of light-light reached 14.3%, and the conclusion nearly come to the same thing with the theory, this result is better than the need to gain 3W green laser of industrialization, and surpasses it 10 percentage.

Electrochemical properties, photoluminescence and electroluminescence properties of a series of copolymer with different content are studied detailedly. The results indicated there is strong energy transfer between blue- and green-yellow light emission units, so only single blue- or green-yellow emission peak appears in the PL and EL spectra and white light-emission cannot get.

These results indicate that the dispersion effect of retardation films are not obvious, and the retardation characteristics of different retarders generated by the same material are almost the same, which would be useful to study how the color liquid crystal display is affected by dispersion effects of retardation films.

本实验得到的蓝光延迟量＝(1-3.5%)绿光延迟量；红光延迟量＝(1+2.6%)绿光延迟量，这为分析延迟膜的色散效应对彩色液晶显示所带来的影响提供了依据。
