Correlating spin and optical properties of quantum emitters in hBN
Nika Teran, Benjamin Whitefield, Nicholas Sloane +3
Optically addressable spin defects in hexagonal boron nitride (hBN) are well suited for near-surface quantum sensing. They offer bright, wavelength-tunable single-photon emission w…
Multi-wavelength Spin Dynamics of Defects in Hexagonal Boron Nitride
Ivan Zhigulin, Nicholas P. Sloane, Benjamin Whitefield +3
Optically addressable solid-state spin defects are essential platforms for quantum sensing and information processing. Recently, single spin defects with combined S = 1 and S = 1/2…
Spatially-resolved coherence of organic molecular spins at room-temperature
Adrian Mena, Nicholas P. Sloane, Max R. Bonengel +1
Molecular spins are a versatile platform for quantum sensing. Not only are the spin-bearing molecules themselves widely tunable, they are also capable of being used as sensors as c…
Photodynamics and Temperature Dependence of Single Spin Defects in Hexagonal Boron Nitride
Benjamin Whitefield, Ivan Zhigulin, Nicholas P. Sloane +3
Quantum emitters in hexagonal boron nitride (hBN) that exhibit optically detected magnetic resonance (ODMR) signatures have recently garnered significant attention as an emerging s…
Mitigating Singlet Exciton Back-Transfer using 2D Spacer Layers for Perovskite-Sensitised Upconversion
Nicholas P. Sloane, Damon M. de Clercq, Md Arafat Mahmud +7
Photon upconversion has potential applications in light-emitting diodes, photocatalysis, bio-imaging, microscopy, 3D printing, and photovoltaics. Bulk lead-halide perovskite films…
Revealing localised dark-exciton populations in 2D perovskites via magneto-optical microscopy
Christopher G. Bailey, Adrian Mena, Tik Lun Leung +5
The successful development of optoelectronic devices is contingent on a detailed understanding of interactions between light and excited energy states in photoactive materials. In…
