White light generation controlled by changing the concentration of silver nanoparticles hosted by Ho<sup>3+</sup>/Tm<sup>3+</sup>/Yb<sup>3+</sup> doped GeO<inf>2</inf>-PbO glasses
(2015-05-02)
Frequency upconversion (UC) experiments were performed with GeO<inf>2</inf>-PbO glasses, containing silver nanoparticles (NPs), doped with holmium (Ho<sup>3+</sup>), thulium (Tm<sup>3+</sup>) and ytterbium (Yb<sup>3+</sup>) ...
White emission in polymer light-emitting diodes: color composition by single-layer electroluminescence and external photoluminescence component
(Elsevier BVAmsterdam, 2014-09)
White emitting devices were obtained through a single component system by combining two materials with different emission properties: a greenish electroluminescent polymer, known as poly[(9,9-dioctylfluorenyl-2,7-diyl)-a ...
SURMOF Devices Based on Heteroepitaxial Architectures with White-Light Emission and Luminescent Thermal-Dependent Performance
(Wiley-VCH, 2020-12)
A new set of Ln-MOF (lanthanide-metal-organic framework) thin films, known as Ln-SURMOFs (surface-supported MOFs), is fabricated with a layer-by-layer, in order to generate solid-state white-lighting devices. A three-component ...
Role of white light intensity and photoperiod during retail in broccoli shelf-life
(Elsevier Science, 2020-05)
White light illumination during retail has been suggested as a simple, non-chemical way to extend the shelf-life of green vegetables. Unfortunately, the influence that key factors like radiation intensity and photoperiod ...
How to Tailor Structural Colors for Extended Visibility and White Light Generation Employing Direct Laser Interference Patterning
(Wiley VCH Verlag, 2019-07)
The appearance of a surface can be controlled by creating periodic microstructures designed to diffract light and produce structural colors. Nevertheless, since structural coloration is based on diffraction, the produced ...
Longer wavelengths of light improve the growth, intake and feed efficiency of individually reared juvenile pikeperch Sander lucioperca (L.)
(Wiley-Blackwell Publishing, Inc, 2009-05-22)
We tested the effects of monochromatic light on the specific growth rate (SGR), feed intake and feed efficiency (FE) of juvenile pikeperch, Sander lucioperca (L.). Pikeperch were reared individually for 42 days in aquaria ...
Aluminum phosphate particles containing closed pores. Preparation, characterization, and use as a white pigment

White light from annealed porous silicon: Broadband emission from violet to the near infrared
(Elsevier Science, 2015-03)
We report white light emission under UV excitation from porous silicon (PS) samples annealed at different temperatures and surrounding atmospheres. The photoluminescence (PL) spectra show a broad emission from ultraviolet ...
Continuous white-blue LED light exposition delays postharvest senescence of broccoli
(Elsevier Science, 2016-01)
In this work, the impact of low intensity (20 μmol m-2 s-1) continue illumination with white and blue light-emitting diodes (WB LED) on the shelf life of broccoli heads stored at 5 °C or at 22 °C was assessed. At both ...
