Interactive patterns are able to promote the notion of reusability in groupware application development. Hence, these patterns support the comprehensiveness of both the interaction design and implementation while easing code modification for groupware application. Groupware is used to describe a broad range of technologies that support person-to-person collaboration. How to design and develop a groupware in an effective manner remains a research question worth exploring. This paper introduces a reusable method, patterns, to develop a single shared display application. Nine different interactive patterns that allow participants to interact collaboratively or non-collaboratively in a single shared display application are introduced in this paper. This is followed by the presentation of our quantitative results on the usability of the interactive patterns and the reusability of the patterns in designing and maintaining a single shared display application. From the results, not only are the patterns useful and easy to understand, the patterns actually ease the process of designing and maintenance during the application development under a single shared display.

The electroluminescent characteristics of blue organic light-emitting diodes （BOLEDs） fabricated with doped charge carrier transport layers are analyzed. The fluorescent blue dopant BCzVBi is doped in an emissive layer, hole transport layer （HTL） and electron transport layer （ETL）, respectively, to optimize the probability of ex- citon generation in the BOLEDs. The luminance and luminous efficiency of BOLEDs made with BCzVBi-doped HTL and ETL increase by 22% and 17% from 11,683 cd/m2 at 8.5 V and 6.08 cd/A at 4.0 V to 14,264 cd/m2 at 8.5 V and 7.13 cd/A at 4.0 V while CIE coordinates of （0.15, 0.15） of both types of BOLEDs remained unchanged. The electron mobility of BCzVBi is estimated to be 1.02 × 10-5 cm2/Vs by TOF.

多孔硅在室温下发出光致荧光展现了硅用作光电子材料和显示技术材料的前景。掺入希土元素可以改善硅的发光性能。本文首次报道多孔硅掺希土的一种新的电化学掺杂方法——恒电位电解，和一种希土硝酸盐－支持电解质－有机溶剂的新电解体系。这一方法和体系的特点是通过采用适当外加电压来控制电解产物，提高掺入的希土浓度，提高发光强度；同时可避免析出使发光不稳定的产物，提高发光稳定性。优化了阳极氧化制备多孔硅的条件和阴极还原制备掺镨多孔硅的条件（镨化合物浓度、溶剂、离子强度、电解电压、时间），获得了光致发光强度高于多孔硅的掺镨多孔硅，并讨论了多孔硅和掺镨多孔硅的光致发光机制。
