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 ...
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 ...
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 ...
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 ...
White light and multicolor emission tuning in Ag nanocluster doped fluorophosphate glasses
(2017-01-01)
The emission properties of Ag nanoclusters (Ag NCs) dispersed in a transparent fluorophosphate glass host have been studied. The as-prepared glass shows that the Ag NCs emit a broad white emission band almost covering the ...
Polyfluorene based blends for white light emission
(Elsevier BVAmsterdam, 2011-09)
Single layer white light emitting diodes were constructed with blends containing as blue emitter and matrix host poly(9,9-dihexyl-2,7-fluorene) (LaPPS10), and the green and red emitters poly[(9,9-dihexyl-9H-fluorene-2,7- ...
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 ...
Multiwavelength visible and white light generation by upconversion emission in Ho/Tm/Yb triply doped fluorogermanate glass-ceramic
(Soc Glass Technology, 2009-02-01)
Energy transfer excited multiwavelength visible upconversion emission and white light generation is described in a single sample of PbGeO(3)-PbF(2)-CdF(2) glass-ceramic triply doped With Ho/Tm/Yb under single infrared laser ...
