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.

随着移动应用高清晰度屏幕的大规模工业化发展，有机发光器件(OLED)已经成为一项非常成熟的技术。然而，一些高端具有挑战性的问题仍然没有得到解决。该计划的长期目标是推动OLED技术超越当今的限制。即建造和示范直接注入有机激光器、按需单光子有机室温发射器和圆形发光二极管。 在有机二极管中实现注入激光是目前有机电子领域的研究热点。世界上十几个领先的研究小组正在积极寻找在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。有机材料中的等离子体对单光子和偏振定制有机电致发光器件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开发开辟新的途径。如果成功，该计划将迅速实现经济上的自我可持续，因为它预计将对信息技术产生重大影响。在适当的知识产权保护下，它将刺激加拿大传感器、量子信息和显示器领域的新初创企业的创建。有机电子设备易于加工，并可集成到其他产品中。所有电子行业都将从我们计划的创新中受益，就像大约20年前开发出稳定的室温蓝色激光二极管时一样。 该计划的短期可公布目标是：开发稀土络合物功能化发光二氧化硅核壳纳米粒子；开发四分之一和半波厚的有机发光二极管；开发分布式反馈光栅耦合结构；对正在研究的器件进行表征和建模。研究目标是根据该小组以前的探索赠款项目所取得的最新成果来设计的。 六名硕士和博士研究生将在该计划下共同工作。他们将研究：稀土荧光粉功能化的核-壳纳米颗粒；高效大电流垂直发射OLED；手性等离子体栅外耦合结构；分布式反馈结构中的连续波受激发射和激光；OLED中的单光子发射；分布式反馈等离子体增强纳米颗粒辅助OLED中的注入激光。
