新一代的光存储将从目前广泛使用的红光波段向蓝光波段发展。
In LD pumped intracavity frequencydoubled blue laser,lownoise stable output could be realize by using two identically crossed placed doubler and one Polarized plate which could successively eliminate the coupling between different modes and the scomponents and the pcomponents through the mode competing and the selective loss.
在LD泵浦Nd:YAG腔内倍频全固体蓝光激光器中采用两个倍频晶体和偏振片技术,通过谐振腔的模式竞争和偏振片的选择性损耗成功地抑制激光器中模式之间的耦合和同一频率中s、p偏振分量之间的耦合,使激光器实现稳定的低噪声功率输出。
The formation of intermolecular aggregation is the main reason for the phenomena that the photoluminescence (PL) efficiency of trimeric phenylenvinylene (TPV) and its derivatives, which are bright pure blue emitters, is much weaker in solid state than that in dilute solution (over 90%).

In this letter blue TEOLEDs based on the blue emissive material,4,4′-bis(2,2′-diphenylvinyl)-1,1′-biphenyl,are acquired with the choice of a highly transparent cathode together with the utilization of a light outcoupling layer onto the cathode,in which microcavity effects,especially for multiple-beam interference,are restrained by decreasing the reflectivity of the cathode.
针对顶发射有机发光二极管(TEOLEDs)中的微腔效应会增加蓝光波段TEOLEDs的制作难度这一问题,提出利用高透明金属阴极并结合在阴极表面生长增透膜的方法来减小二极管阴极的反光性,从而抑制二极管中的微腔效应(这里主要是指多光束干涉);同时利用宽角干涉对器件结构进行设计来改善二极管的蓝光强度,制备了基于有机蓝光材料4,4-′bis(2,2-′diphenylvinyl)-1,1-′biphenyl的顶发射有机发光二极管;优化了增透膜的厚度,研究了增透膜对于二极管电光性能的影响;得到了性能(亮度、效率、色纯度等)可以与底发射有机发光二极管相比的蓝光波段TEOLEDs。
Wide-gap materials are widely used in OLEDs, such as short wavelength light-emitting (blue and UV) layers, most hosts for electrophoshporescence, some hosts for electrofluorescence (especially for blue ones), and charged carrier and exciton blocking.
针对不同的应用目的合成更有效的宽带隙有机材料对提高OLED的性能而言是非常重要的,同时蓝光材料和器件的研究是目前OLED研究的一个关键。
