Helioseismic analysis of the solar flare-induced sunquake of 2005 January 15 [PDF]
, 2006 We report the discovery of one of the most powerful sunquakes detected to date, produced by an X1.2-class solar flare in active region 10720 on 2005 January 15.

Cluster‐Glass for Low‐Cost White‐Light Emission
Advanced Materials, 2022 AbstractThe development of efficient and high‐brilliance white‐light sources is an essential contribution to innovative emission technologies. Materials exhibiting strong nonlinear optical properties, in particular second‐harmonic generation (SHG) or white‐light generation (WLG), have therefore been investigated with great activity in recent times ...

A Nova Outburst Powered by Shocks [PDF]
, 2017 Classical novae are runaway thermonuclear burning events on the surfaces of accreting white dwarfs in close binary star systems, sometimes appearing as new naked-eye sources in the night sky.

Organic Light Emitting Diodes for White Light Emission [PDF]
, 2010 White light sources based on OLEDs are efficient and clean and have the potential to replace the existing lighting system based on incandescent lamp and discharge tubes. Even though the technology has developed to a stage where it can be commercialized, there are many basic issues relating to material science which are not clearly understood and very ...

White‐Light‐Driven Resonant Emission from a Monolayer Semiconductor
Advanced Materials, 2022 AbstractResonant emission in photonic structures is very useful to construct all‐photonic circuits for optical interconnects and quantum computing. Optical generation of most resonant‐emitting modes in photonic structures is obtained by coherent pumping rather than incoherent illumination.

Physical Properties of White-Light Sources in the 2011 Feb 15 Solar Flare [PDF]
, 2014 White light flares (WLFs) are observational rarities, making them understudied events. However, optical emission is a significant contribution to flare energy budgets and the emission mechanisms responsible could have important implications for flare ...

Laser Diode Induced Lighting Modules [PDF]
, 2016 Laser diodes have the potential of becoming the light engines of future lighting technology since they have negligible efficiency droop factor, unlike light emitting diodes.

Interplay between multiple scattering, emission, and absorption of light in the phosphor of a white light-emitting diode [PDF]
, 2013 We study light transport in phosphor plates of white light-emitting diodes (LEDs). We measure the broadband diffuse transmission through phosphor plates of varying YAG:Ce$^{3+}$ density.

White Light Emission from Fluorescent SiC with Porous Surface [PDF]
Scientific Reports, 2017 AbstarctWe report for the first time a NUV light to white light conversion in a N-B co-doped 6H-SiC (fluorescent SiC) layer containing a hybrid structure. The surface of fluorescent SiC sample contains porous structures fabricated by anodic oxidation method.
