Blue organic seven segment display based on poly (9,9-dioctyfluorene)with β-phase emission [PDF]
, 2010 In this work, organic seven segment displays based on poly(9,9-dioctyfluorene), PFO, have been fabricated. PFO has consolidated as an attractive material for PLEDs due to its efficient blue emission [1] and high hole mobility. Additionally, PFO has a

Balancing Charge Injection for Enhanced Efficiency in Inverted InP Quantum Dot Light‐Emitting Diodes
Advanced Quantum Technologies, EarlyView.This study presents a charge injection control strategy for indium phosphide (InP)‐based quantum dot light‐emitting diodes (QLEDs) using a poly(4‐vinylpyridine) (PVPy) interlayer. The optimized structure doubled the external quantum efficiency (EQE) while maintaining luminance, highlighting the importance of balanced charge transport in cadmium‐free ...

Luminance cues constrain chromatic blur discrimination in natural scene stimuli [PDF]
, 2013 Introducing blur into the color components of a natural scene has very little effect on its percept, whereas blur introduced into the luminance component is very noticeable.

Woody cover and geology as regional‐scale determinants of semi‐arid savanna stability
Remote Sensing in Ecology and Conservation, EarlyView.Savannas are vital for global biodiversity and carbon storage, yet their responses to climate change and human activity remain uncertain. Using remote sensing time series and Bayesian Linear Models, we show that drought resistance and resilience vary regionally, shaped by complex interactions between geology, woody cover, fire regimes, past climate ...

Vegetation hot spot signatures from synergy of DSCOVR EPIC, Terra MISR, MODIS and geostationary sensors [PDF]
, 2019 It has been widely recognized that the hotspot region in Bidirectional Reflectance Factors (BRF) of vegetated surfaces represents the most information-rich directions in the directional distribution of canopy reflected radiation.

Advancing the mapping of vegetation structure in savannas using Sentinel‐1 imagery
Remote Sensing in Ecology and Conservation, EarlyView.As vegetation structure monitoring is important for the understanding and conservation of savanna ecosystems, we explored the utility of C‐band synthetic aperture radar imagery for mapping both grassland and woody vegetation structure in the Greater Serengeti‐Mara Ecosystem.

Retrieval of the optical properties of tropospheric aerosols over Athens, Greece combining a 6-wavelength Raman-lidar and the CALIPSO VIS-NIR lidar system: Case-study analysis of a Saharan dust intrusion over the Eastern Mediterranean [PDF]
, 2007 The National Technical University of Athens (NTUA) 6-wavelength (355, 387, 407, 532, 607 and 1064 nm) Raman lidar system has been used to derive the aerosol optical properties (e.g. the lidar ratio, the aerosol backscatter and extinction profile) and the
