Post-doctoral position – Recruitment No 23/2025

Poste Post-doctoral – Pologne

Poste à pourvoir : Post-doctoral position – Recruitment No 23/2025

Entreprise : Institut de Chimie Physique, Académie Polonaise des Sciences

Description du poste :

Le poste de post-doctorant est proposé au sein de l’Institut de Chimie Physique de l’Académie Polonaise des Sciences dans le cadre du projet SONATA 20 (N° 2024/55/D/ST5/02865). Ce projet, dirigé par le Dr Samrat Das Adhikari, se concentre sur l’étude des pérovskiques émettant une lumière bleue pure. Ce type de matériau présente un fort potentiel pour les technologies d’éclairage de nouvelle génération, mais il fait face à des défis importants en termes de performance d’électroluminescence (EL) et d’efficacité quantique externe (EQE), qui doivent rivaliser avec les matériaux rouges et verts.

Les défis incluent des états de piégeage profonds, la ségrégation de phase, le chauffage Joule, et une largeur spectrale d’émission qui compliquent le développement de dispositifs LED bleus répondant aux normes de haute pureté chromatique (Rec. 2020). Les pérovskiques à base de Ruddlesden-Popper (RP) offrent des avantages considérables comme une facilité de traitement en solution et un coût de formation réduit, engendrant un rendement quantique de photoluminescence (PL QY) élevé et une émission monochromatique dans la plage bleue (~465 nm).

Entitled “Pure Blue-Emitting Perovskites: Structural Analysis and Optimization for LED Applications”
Leader Dr Samrat Das AdhikariBlue-emitting perovskites hold great promise for next generation light-emitting technologies, but they face significant challenges in achieving electroluminescence (EL) performance and high external quantum efficiency (EQE) comparable to their red and green counterparts. Addressing issues such as deep trap states, phase segregation, Joule heating, and broader emission spectra is critical to developing blue PeLEDs that meet the Rec. 2020 standards for high-color-purity displays, enabling their practical implementation and commercialization. Blue emitting perovskites based on 2D Ruddlesden-Popper (RP) perovskites are promising materials offering advantages such as facile and low-cost solution processability, and low formation threshold, which provides the material with high photoluminescence quantum yield (PL QY), PL emission band at pure blue range (~465 nm), narrow emission bandwidth, and strong exciton binding energy, which are potential for the next generation blue LED device technology. This project seeks to advance the field by offering innovative strategies for designing high performance optoelectronic devices, addressing critical challenges in material efficiency and durability.Where to apply E-mailrekrutacja@ichf.edu.plRequirementsResearch Field Chemistry » Physical chemistry Education Level PhD or equivalentResearch Field Engineering » Chemical engineering Education Level PhD or equivalentResearch Field Physics » Applied physics Education Level PhD or equivalentResearch Field Physics » Electronics Education Level PhD or equivalentResearch Field Physics » Solid state physics Education Level PhD or equivalentSkills/QualificationsThe successful candidate will work on:
