Eu(II)-Activated Silicates for UV Light-Emitting Diodes Tuning into Warm White Light
(2020-08-01)
White-light-emitting diodes (WLEDs) are the main white light source for general lighting due to high-luminous efficacy (>150 lm W−1), long lifespan (5 × 104 h), and environmentally friendly properties. Despite the current ...
Red Light Stimulates Feeding Motivation in Fish but Does Not Improve Growth
(2013-03-14)
Nile tilapia fish were individually reared under similar light levels for 8 weeks under five colored light spectra (maximum wavelength absorbance): white (full light spectrum), blue (~452 nm), green (~516 nm), yellow (~520 ...

Evaluation of growth and motility in non-photosynthetic Azospirillum brasilense exposed to red, blue, and white light
(Springer, 2020-07)
Azospirillum brasilense is a non-photosynthetic rhizobacterium that promotes the growth of plants. In this work, we evaluated the effects of different light qualities on the growth, viability, and motility in combination ...
Dy3+/Tb3+-codoped tunable warm light-emitting fluorogermanate glass phosphor
(2016-11-01)
Polychromatic tunable visible light emission in the region of the low correlated color temperature range using Dy3+/Tb3+ codoped PbGeO3:PbF2:CdF2 glass phosphor under UV-blue LED light excitation is presented. The glass ...

Pulses of low intensity light as promising technology to delay postharvest senescence of broccoli
(Elsevier Science, 2018-08)
Visible light irradiance may be a useful technology to delay postharvest senescence of green vegetables. In this work, we studied the effects of low-intensity white, red and far red light pulses on postharvest senescence ...
Eco-friendly polydimethylsiloxane-based self-supporting film containing europium-polyoxometalate: A flexible luminescent material for white light generation
(Elsevier B.V., 2018-09-01)
Lanthanide (Ln(3+))-doped suitable matrices exhibit unique luminescent properties which are important for applications in optoelectronic devices. Most of the Ln(3+)-based luminescent materials are, however, prepared in ...
