We would like to congratulate Martin McLaren on receiving the IOP Technician Award. He received this award for his work as technical manager, overseeing operations of the Centre for Designer Quantum Materials since its inception. Congratulations Martin! www.iop.org/about/awards...

Yesterday the School of Physics and Astronomy held the Wilson Sibbett memorial symposium. The day featured several talks from Wilson's friends and colleagues who spoke movingly about his impact on their lives, research, and the field of ultrafast photonics.

Ifor receives the Thomas Young Prize

Congratulations to Ifor on receiving the Thomas Young Prize for world-leading research into OLEDs, organic lasers and their applications in technology and medicine. This prize recognises that he has made distinguished contributions to the field of optics.

Last week's group coffee saw us welcoming two new members to the group, Masato Kato for his PhD and Dr Buddhika Karunathilaka as a Postdoctoral Fellow. Masato brought some green tea chocolates for everyone to enjoy!

This week we are very happy to welcome Dr Buddhika Karunathilaka to the group. He will be supervised by Prof Ifor Samuel and Prof Graham Turnbull, and his research will focus on developing organic lasers that operate under continuous-wave (CW) conditions.

Ifor attended the Optical Probes meeting in Fukuoka last week and gave an invited talk. Also attending were four former OSC members who now lead their own research groups (Prof John Lupton, Prof P. Rajamalli, Dr Gordon Hedley and Prof Paloma dos Santos).

This week we are pleased to welcome Yamini Sharma to the group. She is visiting us from the IPCMS in Strasbourg. During her one month stay she will be researching the photophysics of TADF materials.

Today is international day in the school of Physics and Astronomy. It is a great opportunity to celebrate the diversity in the OSC that helps make our research world class.

Congratulations to the authors of the paper “OLED illuminated metasurfaces for holographic image projection” which has just been published with Light: Science & Applications. DOI: doi.org/10.1038/s413...

We are happy to welcome Chico Paulics Bresler to the group for his PhD on the HISOPE project, researching fast organic optoelectronic materials and devices. He is jointly supervised by Prof Ifor Samuel and Prof Graham Turnbull.

Congratulations to Jingxiang, Dongyang, & Yan for their paper accepted in @angewandtechemie.bsky.social ,(doi.org/10.1002/anie...) work in collab with Ifor Samuel's group and @jeannecrassousiscr.bsky.social ⚗️🧪@standrewschem.bsky.social @standrewsosc.bsky.social #TADFSolutions

This week we are pleased to welcome Shintaro Kohata to the group. He is visiting us from the Adachi lab at Kyushu University. During his two month stay he will be investigating photophysics in novel TADF systems.

The group, sat around the table, celebrating Ifor's birthday!

Today we celebrated Ifor's birthday with some cake and pastries. Happy birthday Ifor, we hope you enjoy the presents!

Last month, Aswin attended the Algal BBB conference in Arizona, US. He gave a talk on 'Unlocking the optimal wavelength for different growth phases for Arthrospira platensis in a cylindrical airlift photobioreactor'.

Congratulations to Liam, Kou, and our collaborators at the University of Cambridge, led by Harald Haas for the paper "Visible light communication using thermally activated delayed fluorescent OLEDs". DOI: lnkd.in/er_6ZuiQ

Recently Sagarika attended the International Meeting on Chemical sensors in Freiburg, Germany where she presented some of her recent work.

Working with the team of Prof Harald Haas we have demonstrated a record communication rate in OLEDs. The new paper "High-speed organic light-emitting diodes based on dinaphthylperylene achieving 4-Gbps communication" published with Advanced Photonics. DOI: doi.org/10.1117/1.AP...

This week Ifor gave presented work on high brightness OLEDs and lasers at the Excited State Processes conference in Santa Fe, New Mexico. Former group member Prof John Lupton spoke directly after him.
