Blue and white light emission from zinc oxide nanoforests

Beilstein Journal of Nanotechnology, 2015
Blue and white light emission is observed when high voltage stress is applied using micrometer-separated tungsten probes across a nanoforest formed of ZnO nanorods.

Sun-as-a-star Observation of White-Light Flares

, 2011
Solar flares radiates energy at all wavelengths, but the spectral distribution of this energy is still poorly known. White-light continuum emission is sometimes observed and the flares are then termed "white-light flares" (WLF).

Understanding the white-light flare on 2012 March 9 : Evidence of a two-step magnetic reconnection

, 2012
We attempt to understand the white-light flare (WLF) that was observed on 2012 March 9 with a newly constructed multi-wavelength solar telescope called the Optical and Near-infrared Solar Eruption Tracer (ONSET).

From X-ray dips to eclipse: Witnessing disk reformation in the recurrent nova USco [PDF]

, 2011
The 10th recorded outburst of the recurrent eclipsing nova USco was observed simultaneously in X-ray, UV, and optical by XMM-Newton on days 22.9 and 34.9 after outburst.

The 2010 August 01 type II burst: A CME-CME Interaction, and its radio and white-light manifestations

, 2012
We present observational results of a type II burst associated with a CME-CME interaction observed in the radio and white-light wavelength range. We applied radio direction-finding techniques to observations from the STEREO and Wind spacecraft, the ...

Photoluminescence studies of a perceived white light emission from a monolithic InGaN/GaN quantum well structure [PDF]

, 2015
In this work we demonstrate by photoluminescence studies white light emission from a monolithic InGaN/GaN single quantum well structure grown by metal organic chemical vapour deposition.

Luminescent characteristics of Dy3+-doped polymethyl methacrylates for white light-emitting diode

Results in Physics, 2018
To explore white-light-emitting materials, a series of Dy3+-doped polymethyl methacrylate (PMMA) samples are prepared by polymerization method. Excitation spectra and emission spectra are experimentally investigated.
