In this term of project to realize organic thin layer laser device by photonic crystal (P Cs), we studied about the following that divided this project into an approach based our research results of organic light emitting diodes (O L E Ds) until now and another approach from P Cs by the aggregation of spherical particles to their optical resonators, and in both approaches we obtained important results to plan the development to organic thin layer laser devices.1. The fabrication of O L E Ds that have the periodic structure with 200 nm lines-and-spaces and their luminescent characteristics we realized O L E Ds that have the periodic structure in the order of wavelength of light to the direction along the surface of the substrate, and moreover, in the O L E Ds we observed an effect as an optical resonator that light of wavelength corresponded to the pattern period could be resonated and an anisotropic emitting characteristic depended on the liner shape of their emitting areas, and we dem … More onstrated they were quantum effects by the fine periodic structure (in 1998).We realized non-defect periodic structure in the order of wavelength of light in extensive area (> 10 mm × 10 mm) on indium tin oxide films coated on glass substrates by U V holographic interference lithography. By use of this lithographic pattern as a mold for lift-off method, we also realized the fine periodic structure consists of inorganic materials (in 1999).2. The fabrication of three-dimensional P Cs having a complete photonic band gap in the visible wavelength region and their Optical characteristicsBy use of the commercial particles, we found the conditions to control the aggregations of spherical particles (colloidal crystals), and evaluated the optical characteristics as three-dimensional P Cs having a photonic band gap in the visible wavelength region. By use of the water solution of monodispersed SiO, particles (the mean diameter of 280 nm, the solid concentration of 20 wt%) made in Catalysts & Chemicals Ind. Co., Ltd., at 20℃ and saturated humidity atmosphere it was cast on the hydrophilic glass substrates that were cleaned by 0 plasma, left in and dried, and we found it was possible to control close to the array of the colloidal single crystal consists of a face-centered cubic structure by the condition of drying and the pretreatment of substrate. in their transmission spectra, we observed the attenuation by photonic band gap, and confirmed it was a photonic band effect by the periodicity of two refractive indexes (in 1998).To fabricate of as yet no three-dimensional P Cs having a complete photonic band gap in the visible wavelength region, we synthesized monodispersed Ti0 particles of higher refractive index material, studied about the improvement of the monodispersibility. For the synthesis of monodispersed spherical oxide particles, we adopted the alkoxide process. Firstly the dehydrated CィイD22ィエD2HィイD25ィエD2OH solution of distilled water (after mixture, 0.3 mol/l) was mixed as the dehydrated CィイD22ィエD2HィイD25ィエD2OH solution of highly purified Ti(OCィイD22ィエD2HィイD25ィエD2)ィイD24ィエD2 (after mixture, 0.1 mol/l) was stirred, and the mixed solution was advanced by the hydrolysis and the polycondensation. The solution was aged at 50 ℃ for 5 h. Secondly the TiOィイD22ィエD2 particles were sparated from the solution by a centrifuge and washed with the dehydrated CィイD22ィエD2HィイD25ィエD2OH by a ultrasonic cleaner, and the TiOィイD22ィエD2 particles were dispersed in an ammonia water (pH 11). Consequently we synthesized Ti0ィイD22ィエD2 particles (amorphous and porous hydrate) consists of the geometarical standard deviation of 1.1 and the mean diameter of 500 nm. And by the variations of the concentration in the dehydrated CィイD22ィエD2HィイD25ィエD2OH solution of highly purified Ti(OCィイD22ィエD2HィイD25ィエD2), or the temperature in aging, we found it was possible to control the mean diameter. In ZnOィイD22ィエD2 and TaィイD22ィエD20ィイD25ィエD2 particles, it was also found that the same method was useful (in 1999). Less

在本项目利用光子晶体（pcs）实现有机薄层激光器件的研究中，我们进行了以下方面的研究，将本项目分为基于我们迄今为止对有机发光二极管（O L E d）的研究成果的方法和基于球形粒子向其光学谐振腔聚集的pcs的方法，两种方法都获得了对规划有机薄层激光器件发展的重要成果。通过对具有200 nm线间距周期结构的光电二极管的制备及其发光特性的研究，实现了沿衬底表面方向沿光波长顺序具有周期结构的光电二极管。作为光学谐振器，我们观察到与图案周期对应的波长的光可以共振，其发射区域的线性形状决定了其发射特性的各向异性，并通过精细周期结构（1998）进一步证明了它们是量子效应。利用紫外全息干涉光刻技术，在玻璃基板上涂覆的氧化铟锡薄膜上实现了大面积（bbb10 mm × 10 mm）光波长顺序的无缺陷周期结构。通过使用这种光刻图案作为提升方法的模具，我们还实现了由无机材料组成的精细周期结构（1999年）。利用商业粒子，我们找到了控制球形粒子（胶体晶体）聚集的条件，并评价了在可见光区域具有光子带隙的三维光子Cs的光学特性。采用催化剂化工股份有限公司生产的单分散二氧化硅（SiO）颗粒（平均直径为280 nm，固体浓度为20 wt%）的水溶液，在20℃和饱和湿度气氛下，将其浇铸在亲水性玻璃基板上，用等离子体清洗后放置干燥。通过对基质的干燥和预处理，我们发现可以控制胶体单晶阵列接近于面心立方结构。在它们的透射光谱中，我们观察到了光子带隙的衰减，并通过两个折射率的周期性证实了这是光子带效应（1998）。为了制备目前还没有在可见光区具有完整光子带隙的三维光子晶体，我们合成了高折射率材料的单分散Ti0粒子，研究了单分散性能的提高。对于单分散球形氧化物颗粒的合成，我们采用醇盐法。首先脱水CィイD22摊位ィエD2HィイD25ィエD2OH蒸馏水溶液(混合后,0.3 mol / l)是混合脱水CィイD22摊位ィエD2HィイD25ィエD2OH解决高纯度钛(OCィイD22摊位ィエD2HィイD25ィエD2)ィイD24ィエD2(混合后,0.1 mol / l)搅拌,混合解决方案是先进的水解和缩聚。解决方案是年龄在50℃5 h。其次TiOィイD22摊位ィエD2粒子被离心机sparated从解决方案和清洗脱水CィイD22摊位ィエD2HィイD25ィエD2OH超声波清洁,和TiOィイD22摊位ィエD2粒子分散在一个氨水(pH值11)。因此我们合成Ti0ィイD22摊位ィエD2粒子(非晶和多孔水合物)由geometarical标准差为1.1,平均直径500纳米。并通过对脱水后的C′′φ D22′′φ D2H′′φ D25′′φ D2OH溶液中高纯度Ti（OC′′φ D22′′φ D2H′′φ D25′′φ D2）浓度的变化，以及时效过程中温度的变化，发现可以控制平均直径。在氧化锌（ZnO）和Ta （Ta）中也发现了同样的方法（1999年）。少
