Dy3+ White Light Emission Can Be Finely Controlled by Tuning the First Coordination Sphere of Ga3+/Dy3+ Metallacrown Complexes.

Journal of the American Chemical Society, 2020
Single lanthanide(III) ion white light emission is in high demand since it provides the advantage of requiring only one chromophore for the control of the color.

Protonable pyrimidine derivative for white light emission

RSC Advances, 2015
The protonation of a blue emitting pyrimidine resulted in the formation of an orange emissive acidified form. In adequate proportion of neutral and protonated forms, white light emission is observed both in solution and in polystyrene thin film.

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Unconventional Production of Bright White Light Emission by Nd-Doped and Nominally Un-Doped $\hbox{Y}_{2}\hbox{O}_{3}$ Nano-Powders

IEEE Photonics Journal, 2014
We report the production of a broad band (ranging from 400 to 900 nm) white light following the monochromatic infrared light (803.5 and 975 nm) excitation of both nominally un-doped and Nd3+-doped Y2O3 nano-powders, even up to 20% of Nd3+ content ...

A White Light Megaflare on the dM4.5e Star YZ CMi

, 2010
On UT 2009 January 16, we observed a white light megaflare on the dM4.5e star YZ CMi as part of a long-term spectroscopic flare-monitoring campaign to constrain the spectral shape of optical flare continuum emission.
