With the massive industrial development of high definition screens for mobile applications, organic light emitting devices (OLEDs) have become a very mature technology. Nevertheless, several high-end challenging issues still remain unsolved. Long-term objective of the program is to push OLED technology beyond today's limits. That is to build and demonstrate direct injection organic lasers, organic room temperature emitters of single photons on demand and circular light emitting diodes. ****The achievement of injection lasing in organic diodes is currently a hot topic in the field of organic electronics. A dozen of leading groups in the world are actively searching for the conditions to reach injection lasing in organic semiconductors. The potential of plasmonics for lasers is currently explored by several teams in Canada and abroad. The potential of plasmonics in organics for single photon and polarization tailored OLEDs has not yet been fully recognized. It is expected that the present research program will open new avenues for research and technological development in these fields. If successful the program will rapidly become economically self-sustainable owing to its expected strong impact on information technologies. With appropriate intellectual property protection, it will stimulate the creation of new startups in the field of sensors, quantum information and displays in Canada. Organic electronic devices are easy to process and to integrate into other products. All the electronic industry will benefit from the innovations of our program, in a similar manner as when stable room temperature blue laser diodes were developed about 20 years ago.****Shorter term, publishable objectives of the program are: to develop rare-earth complex functionalized luminescent silica core-shell nanoparticles; to develop quarter and half-wave thick OLEDs; to develop distributed feedback grating coupling structures; to characterize and model the devices under study. Research objectives were designed on the grounds of recent achievements obtain from previous discovery grant projects in the group. ****Six graduate students at the Master and Doctoral levels will work together under the program. They will study: rare earth phosphor functionalized core-shell nanoparticles; high-efficiency high-current vertical emitting OLEDs; chiral plasmonic grating out-coupling structures; continuous-wave stimulated emission and lasing in distributed feedback structures; single photon emission in OLEDs; injection lasing in distributed feedback plasmon-enhanced nanoparticle assisted OLEDs.**

随着用于移动的应用的高清晰度屏幕的大规模工业发展，有机发光器件（OLED）已经成为非常成熟的技术。然而，一些高端挑战性问题仍然没有解决。该计划的长期目标是推动OLED技术超越当今的极限。这是建立和展示直接注入有机激光器，有机室温发射器的单光子的需求和圆形发光二极管。* 在有机二极管中实现注入激光是目前有机电子学领域的一个热门课题。国际上有十几个研究小组正在积极探索有机半导体中实现注入激光的条件。目前，加拿大和国外的几个团队正在探索等离子体激元用于激光的潜力。有机物中的等离子体激元用于单光子和偏振定制OLED的潜力尚未得到充分认识。预计目前的研究计划将为这些领域的研究和技术发展开辟新的途径。如果成功，该计划将迅速成为经济上自我可持续的，由于其预期的强大影响，信息技术。通过适当的知识产权保护，它将刺激加拿大传感器，量子信息和显示器领域的新创业公司的创建。有机电子器件易于加工和集成到其他产品中。所有电子行业都将受益于我们计划的创新，就像大约20年前开发稳定的室温蓝色激光二极管一样。该计划的短期可持续目标是：开发稀土复合物功能化发光二氧化硅核壳纳米颗粒;开发四分之一和半波长厚的OLED;开发分布式反馈光栅耦合结构;表征和模拟正在研究的器件。研究目标是根据该小组以前的发现资助项目所取得的最新成果设计的。* 六名硕士和博士级别的研究生将在该计划下共同工作。他们将研究：稀土磷光体功能化核壳纳米颗粒;高效高电流垂直发射OLED;手性等离子体光栅外耦合结构;分布反馈结构中的连续波受激发射和激光; OLED中的单光子发射;分布反馈等离子体增强纳米颗粒辅助OLED中的注入激光。**
