Strain relaxation in InGaN/GaN micro-pillars evidenced by high resolution cathodoluminescence hyperspectral imaging [PDF]
, 2012 A size-dependent strain relaxation and its effects on the optical properties of InGaN/GaN multiple quantum wells (QWs) in micro-pillars have been investigated through a combination of high spatial resolution cathodoluminescence (CL) hyperspectral imaging

Spatial separation of large dynamical blue shift and harmonic generation [PDF]
, 2006 We study the temporal and spatial dynamics of the large amplitude and frequency modulation that can be induced in an intense, few cycle laser pulse as it propagates through a rapidly ionizing gas. Our calculations include both single atom and macroscopic

Doppler shift of hot coronal lines in a moss area of an active region [PDF]
, 2012 The moss is the area at the footpoint of the hot (3 to 5 MK) loops forming the core of the active region where emission is believed to result from the heat flux conducted down to the transition region from the hot loops. Studying the variation of Doppler

Response of Photonic Hydrogels of Homogeneous Particles to Uranyl Ions in Aqueous Solutions
Photonic Sensors, 2023 We study here the response of photonic hydrogels (PHs), made of photonic crystals of homogeneous silica particles in polyacrylamide hydrogels (SPHs), to the uranyl ions UO 2 2+ in aqueous solutions. It is found that the reflection spectra of the SPH show

Color Point Tuning for (Sr,Ca,Ba) Si2O2N2:Eu2+ for White Light LEDs [PDF]
, 2009 Color point tuning is an important challenge for improving white light LEDs. In this paper, the possibilities of color tuning with the efficient LED phosphor Sr1−x−y−zCaxBaySi2O2N2:Euz2+ (0 ≤ x, y ≤ 1; 0.005 ≤ z ≤ 0.16) are investigated.

Spectrally Stable Blue Light-Emitting Diodes Based on All-Inorganic Halide Perovskite Films
Nanomaterials, 2022 Substantial progress has been made in perovskite light-emitting diodes (PeLEDs), but the fabrication of high-performance blue PeLEDs still remains a challenge due to its low efficiency, spectral instability and short operational lifetime.

Discovery of strongly blue shifted mid-infrared [NeIII] and [NeV] emission in ULIRGs [PDF]
, 2009 We report the discovery of blue shifted (delta(V) > 200 km/s) mid-infrared [NeIII] and/or [NeV] emission in 25 out of 82 ULIRGs (30% of our sample).
