Interplay between multiple scattering, emission, and absorption of light in the phosphor of a white light-emitting diode [PDF]

open access: yes, 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.

Physical Properties of White-Light Sources in the 2011 Feb 15 Solar Flare [PDF]

open access: yes, 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 ...

White Light Emission from Fluorescent SiC with Porous Surface [PDF]

open access: yesScientific 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.

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

open access: yes, 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).
