Publication New Publication: Disentangling the impact of point defect density and carrier localization Green LEDs remain low efficiency compared with their blue counterparts, but are required for future display technology. Power-dependent measurements show that current- rather than defect-management is crucial to improving efficiency.
Publication New Publication: Heterometallic Lanthanide Complexes with Site-Specific Binding that Enable Simultaneous Visible and NIR-emission Lanthanide elements have distinctive and long-lived light emission. Holding multiple lanthanides close together provides a route to creating new biological imaging molecules.
Publication New Publication: Bottom-up, chip-scale engineering of low threshold, multi- quantum well microring lasers Computation with light instead of electricity will increase speed and energy efficiency. We show a route to growing lasers directly onto chips with high repeatability to enable this technology.
Valentina Bonino Visitor: Valentina Bonino (ESRF) Valentina Bonino, beamline scientist at the ESRF in Grenoble, visited the group to discuss collaboration on nanomaterial characterization.
Visit Visitor: Prasana Sahoo (IIT Kharagpur) Group collaborator Prof Prasana Sahoo visited the Photon Science Institute in Manchester to deliver a seminar and discuss future research.
invited talk Invited talk at IUMRS ICAM-ICMAT 2023, Singapore Group PI Patrick was invited to give a talk at the International Union of Materials Research Society meeting in Singapore.

PhD studentship Funded PhD positions available (Home and Overseas) We have new funded PhD opportunities available in the group. These are through two partnerships, with A*STAR in Singapore and IIT Kharagpur in India. These projects are both split-site, and are open to home and exceptional overseas students. They are open now for a September 2023 start. Please check
Hoyeon Choi Congratulations to Hoyeon Choi! A huge congratulations to group PhD Hoyeon Choi for successfully defending his thesis today. Hoyeon's examiners were Sam Bayliss (Glasgow) and David Binks (Manchester). Hoyeon was the fourth postgraduate student through the OMS group, and the first to be impacted by COVID. Nevertheless, he built up a substantial
Stephen Church New Publication: Holistic Nanowire Laser Characterization as a Route to Optimal Design Group postdoc Stephen Church has just had a paper accepted into Advanced Optical Materials. In this work, he reports the study of thousands of individual nanowire lasers, using advanced statistical methods to identify a route to optimization. Photonic integrated circuitry is rapidly emerging as an alternative to electronics for specialist

Lab Photos End-of-year lab cleanup The group assembled in the lab for a final tidy of 2022. The lab is ready for new students and new experiments in 2023!
Featured About us The Optoelectronic Materials Spectroscopy group at the University Manchester focuses on developing experimental, analytical and data-based methodology for novel materials. We use automated experimentation coupled to cutting-edge laser facilities to study nano-lasers, micro-LEDs, graphene-based photodetectors, single quantum dots and emerging materials. We work across disciplines - including physics, chemistry, electronic
Christmas Group Christmas Meal and Hoyeon's thesis submission It was great to have our group Christmas meal in Manchester which coincided with a celebration of Hoyeon’s thesis submission!
Alex Walton Funded PhD project: Correlative operando spectroscopy of electrocatalysts A fully-funded joint PhD project between Dr Alex Walton (Manchester Chemistry) and the Parkinson group is being advertised for a 2023 start. The project is based on correlating fast and slow measurements – optical and photoelectronic studies – of novel electrocatalytic materials. It is well suited for a student with an interest
big-data for nano-electronics Presentation Prize: Stephen Church at Rank Prize Symposium Group postdoc Stephen Church was awarded the “best early-career-researcher” presentation prize at the Rank Prize Symposium meeting in Grasmere. The meeting Nanowire Photonics was chaired by Prof. Martin Dawson (Strathclyde), Prof. Hannah Joyce (Cambridge) and Prof. Michael Johnston (Oxford). Congratulations to Stephen!
