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.

The UV and IR spectroscopic studies of the monomer films showed that the photoreaction ratio of monomer (about 50%) was higher than the corresponding photosensitive polymer (about 10%, PVCi). The polarized IR spectra proved that obvious anisotropic absorption was displayed in the irradiated photosensitive film. With polarizing microscopy method, we found that these kinds of photoalignment films exhibited good alignment ability, and the stability of the photoalignment film could reach about 100℃. 2 A photosensitive self-assembled monolayer was fabricated that contained photo-cycloadditable groups, such as, coumarin and cinnamate. The reaction process were detected by contact angle method because the IR absorption of monolayer was very weak. The photosensitive self-assembled monolayer promote uniform alignment of nematic liquid crystals by LPUV, and it thermal stability could reach about 130℃. 3 A cationic bolaform amphiphiles was synthesized that had two photosensitive double bonds, and can be polymerized by ultraviolet. A layer-by-layer self-assembled deposition film was prepared in aqueous solution by using this material and poly (sodium 4-styrenesulfonate). The UV-Vis. spectra proved that the multilayers film was uniform and layer-by-layer. When LPUV irradiated the film, the photopolymerizable double bond underwent [2+2] cycloaddition, and the production of the reaction distributed along the polarized direction of incident LPUV. Polarized UV-Vis. spectra indicated that the irradiated self-assembled multiplayer film was anisotropic, and the dichromic ration is about 0.09, it is higher than the spin-coating method of photosensitive polymer or monomer. We used this anisotropic film as alignment layer of nematic liquid crystals, and obtained a uniform and stability alignment result, the static contrast ratio is about 100, which is very close to application of liquid crystal device. This thesis is an instance that the photochemical material was used in the physics region of liquid crystals, the route that was from photosensitive monomer, self-assembled monolayer film to self-assembled multiplayer film was undergone, by this logical research method photoailgnment of liquid crystal was extended and consummated.
