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 ...
A spectroscopic experimental and semi-empirical study of [Eu(salen)2] as a red-emitter for phosphor-converted UV LED
(2021-10-01)
Most of commercial WLEDs have a lack of red-emission component resulting in cool white illumination. Aiming this issue, in this paper, we present the synthesis of [Eu(salen)2] with a Schiff base type ligand, the salen ...
Effect of different synthesis methods on the morphology, optical behavior, and superior photocatalytic performances of Ag3PO4 sub-microcrystals using white-light-emitting diodes
(Elsevier B.V., 2019-05-15)
In this paper, we report on the superior photocatalytic properties of silver orthophosphate (Ag3PO4) sub-microcrystals prepared using different synthesis methods: precipitation (PM), precipitation-calcination (PM-C), and ...
Syntheses and characterization of Schiff base ligands and their Ir(III) complexes as coating for phosphor-converted LEDs
(2020-10-01)
Ir(III) complexes find several applications in light conversion molecular devices (LCMD) such as in solid-state lighting (SSL). Although, a couple of blue or green-emitting Ir(III) complexes are found so far, there is a ...
Recent prospects on phosphor-converted LEDs for lighting, displays, phototherapy, and indoor farming
(2021-09-01)
Phosphor-converted white-light-emitting diodes (PC-WLEDs) are the main devices behind solid-state lighting (SSL) for both indoor and outdoor lighting, or backlight of liquid-crystal displays (LCD). Nonetheless, despite the ...
Light-emitting diodes based on Eu3+, Eu2+ or Tb3+-doped silicates for lighting and Circadian rhythm regulation
(Universidade Estadual Paulista (Unesp), 2019-08-30)
Diodos emissores de luz branca (WLEDs) são as principais fontes de luz branca para iluminação e fundo de tela de displays devido ao alto brilho (800 lm) e eficácia luminosa (150 lm·W-1), alto tempo de vida útil (50.000 ...
White-light-emitting KCl:Eu2+/KCN crystal for solid-state lighting devices
(Royal Society of Chemistry - RSCCambridge, 2014)
The optical and colorimetric properties of a KCl:Eu2+/KCN crystal are analyzed in this paper to verify its potential for the development of white-light-emitting diode (WLED) devices. An unusual broad and intense yellow-green ...
