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 ...
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 ...
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 ...
Use of LED light for Brussels sprouts postharvest conservation
(Elsevier Science, 2016-12)
Yellowing is the most evident symptom of senescence in green vegetables during postharvest storage. As chlorophyll synthesis is promoted by blue light, illumination would be a clean alternative to maintain healthier ...
High intensity and red enriched LED lights increased the growth of lettuce and endive
(PagePress, 2022)
Changes in plant responses have been associated with different fractions of the visible spectrum and light intensity. Advances in light-emitting diodes (LED) have enabled the study of the effect of narrow wavelengths on ...
Eu3+ complex/polymer films for light-emitting diode applications
(2019-10-01)
Eu3+ complexes exhibit potential to be applied as the red emitter component of white-light-emitting LEDs due to their intense absorption in the near-UV spectral region and intense red-light emission. However, the main ...
