Welcome to ICOEO-2021

ICOEO-2021 organizing committee with great honor extending you a warm invitation to attend the International Congress on Optics, Electronics, and Optoelectronics 2021 which is slated to held during Nov. 5-7, 2021 in Xi’an, China.

The ICOEO International Conference is a unique platform of Laser, Optics and Photonics, Electronic Components and Technology, and Optoelectronic Devices and Integration, from those in the earliest stages of their careers to people whose research or strides in Optics, Electronics, and Optoelectronics has gained them international recognition. Last year, despite the influence of the epidemic, many foreign scholars were unable to attend in person, still nearly 150 of these professionals choose to attend, present, and learn about the latest advances, meet with colleagues, and strike new collaborations. It is truly where today’s science meets tomorrow’s care. 

The Two-day long agenda has been scheduled to have programs covering keynote Forum, Breakout Sessions, Young Scientists Forum, Poster and Exhibition, University and Industry Park Visits, etc. The congress is aimed to provide a perfect place to meet and discuss innovation, challenges and opportunities to promote the development of this field.

Xi'an is the cradle of ancient Chinese civilization, with a history dating back to 4000 BC. Known as Chang’an in early times, it was the capital of China for eleven dynasties, up to the 9th century. It is from here that caravans started on the Silk Road to Europe, changing the Western world forever. Now the capital of Shaanxi Province, Xi’an is also the political, economic and cultural center of the Northwest, with a population of 2,650,000. You are welcomed to enjoy centuried and rich culture fascinating here outside of the meeting.

Finally, the organizing committee of ICOEO-2021 sincerely invites you to participate in this grand event!

The International Congress on Optics, Electronics, and Optoelectronics 2020 (ICOEO-2020) took place from Nov. 4-6, 2020 in Chengdu, China. The congress was run under the auspices of ISTCI and operated by Four Leaf Clover Event. A total of approx. 120 participants from China attended the conference and 7 speakers are unable to attend in person due to travel restrictions, so sent the video of the speech instead.
ICOEO-2020 mainly focuses on current hot topics of Laser, Optics and Photonics, Electronic Components and Technology, and Optoelectronic Devices and Integration. The program was structured in 14 parallel sessions to give room for the 80+ contributions that were selected by the Scientific Advisory Committee for oral presentations in the fields of: Preparation and Application of Optical Materials; Breaking Research of Optical Technology; Laser Technology and Application; Terahertz Technology; Optical Communications Technology; Optics in Health Care and Biomedical; Electronic Materials; Thin Films and Devices; Piezoelectrics, Ferroelectrics and Pyroelectrics Materials and Technology; Semiconductor Materials and Technology; Optoelectronic Materials; Optical Sensor & Fiber Optic Sensor; Solar Cells.
The Keynote Forum
ICOEO-2020 was opened by keynote speakers Mohamad Sawan, Hong Gao, Chaoyuan Jin, Wenbin Dou, Naosheng Qiao, Dieter Bimberg who brought us a variety of topics. Because the Covid-19 caused travel inconvenience, our Honorary Chairman, Dr. Dieter Bimberg specially sent a video to express congratulations to the conference.
The Parallel Sessions
14 Parallel Sessions surprised us deeply. Dr. Haiding Sun from university of Science and Technology of China in China discussed the recent progress on the development high efficient AlGaN-based optoelectronics, mainly on the high efficient deep-ultraviolet light-emitting diodes grown on large misoriented sapphire substrates, ultraviolet lasers in the form of graded index separated confinement heterostructure (GRINSCH), as well as the high photoresponsive solar-blind photodetectors in the form of AlGaN-based nanowires. Dr. Jianhong Yang, from Institute of Microelectronics, School of Physical Science and Technology, Lanzhou University, has renovated the p-n junction theory in a self-consistent manner by introducing the concept of excess majority carriers. An original design of grazing incidence X-ray spectrometer was reported which could be further implemented to develop the high-resolution spectral diagnostics for Shanghai X-ray Free Electron Laser Project by Dr. Bin Li at Shanghai Advanced Research Institute, Chinese Academy of Sciences in China. Dr. Zhiyuan Zhu from Southwest University, China said at ICOEO-2020: the energy harvesting property and physical-chemical properties detection of food-based microsystem, which provides novel solution to energy problem and forms a fast, simple, flexible, efficient, low-cost, self-powered, environmentally friendly and degradable multifunctional food physical-chemical detection method. Dr. Ji Wang from Piezoelectric Device Laboratory of Ningbo University in China, had a speech on the development of quartz crystal resonators and hope the analysis will be helpful for essential and optimal design parameters for the development of quartz crystal resonators.
