Aditya Sadhanala,Shahab Ahmad,Baodan Zhao,Nadja Giesbrecht,Phoebe Pearce,Felix Deschler,Robert L. Z. Hoye,Karl C. Gödel,Thomas Bein,Pablo Docampo,Siân E. Dutton,Michael De Volder,Richard H. Friend +12 more
TL;DR: High color-purity, tunable LEDs with narrow emission full width at half maxima (FWHM) and low turn on voltages using thin-films of these perovskite materials, including a blue CH3NH3PbCl3 perovSKite LED with a narrow emission FWHM of 5 nm are demonstrated.
Proceedings ArticleDOI
A review of wearable antenna
Nurul Husna Mohd Rais,Ping Jack Soh,Fareq Malek,Shahab Ahmad,Nur Baya Mohd Hashim,Peter Hall +5 more
TL;DR: In this article, the authors present a literature review of wearable antenna technology and provide readers with the background of the wearable antenna that would include about specification of the antenna, material for the antenna and analysis that must be done to design proper wearable antennas.
Journal ArticleDOI
Reduced graphene oxide (rGO) based wideband optical sensor and the role of Temperature, Defect States and Quantum Efficiency
TL;DR: Wavelength-dependent studies shows that proposed rGO based optical sensor performance at low temperature can efficiently operate from visible to near NIR region and power dependent studies establish linear relation between power-density and sensitivity.
Journal ArticleDOI
Real-Time Observation of Exciton-Phonon Coupling Dynamics in Self-Assembled Hybrid Perovskite Quantum Wells.
Limeng Ni,Uyen Huynh,Alexandre Cheminal,Tudor H. Thomas,Ravichandran Shivanna,Ture F. Hinrichsen,Shahab Ahmad,Aditya Sadhanala,Akshay Rao +8 more
TL;DR: In this article, a femtosecond vibrational spectroscopy was performed to obtain a real-time picture of the exciton-phonon interaction and directly identified the vibrational modes that couple to excitons.
Journal ArticleDOI
Photo-Rechargeable Organo-Halide Perovskite Batteries
TL;DR: This photobattery relies on highly photoactive two-dimensional lead halide perovskites to simultaneously achieve photocharging and Li-ion storage and provides simple autonomous power solutions while retaining capacities of up to 100 mAh/g and efficiencies similar to electrodes using a mixture of batteries and solar materials.
