Study on suppression of otoacoustic emissions: lateral domain
(Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2011-09-01)
A pon stimulation by contralateral, ipsilateral or bilateral noise, the medial olivocochlear efferent tract changes the amplitude of otoacoustic emissions relative to the tested ear, reducing or removing it; this resulted ...
White-Light and Yellow/Blue Photoluminescence Emission Based on Dy3+-Doped SiO2–Gd2O3 Composites
(2016-09-01)
This work attempts to obtain Dy3+-doped SiO2–Gd2O3 by sol–gel process, with a molar ratio of 70Si4+–30Gd3+ and Dy3+ concentrations of 0.1, 0.3, 0.5, and 1 mol%. Heat treatment at temperatures of 1000°C, 1100°C, 1200°C, and ...
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 ...
Chemical diversity in lead-free, layered double perovskites: A combined experimental and computational approach

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 ...
Enhancement of the photocatalytic activity and white emission of CaIn2O4 nanocrystals

Towards a white-emitting phosphor Ca10V6O25 based material
(2020-04-01)
To achieve a stable material capable of white-light emission, we fabricated Ca10V6O25 by both co-precipitation (CP) and microwave-assisted hydrothermal (MAH) methods at different temperatures. The effects of structural ...
Red-green-blue upconversion emission and energy-transfer between Tm3+ and Er3+ ions in tellurite glasses excited at 1.064 mu m
(Elsevier B.V., 2003-02-15)
Red, green, and blue emission through frequency upconversion and energy-transfer processes in tellurite glasses doped with Tm3+ and Er3+ excited at 1.064 mum is investigated. The Tm3+/Er3+-codoped samples produced intense ...

On the origin of white photoluminescence from ZnO nanocones/porous silicon heterostructures at room temperature
(Elsevier, 2014-12)
ZnO nanocones were grown on porous silicon (PS) by vapor transport at different temperatures and O2 flow rates without metal nanocatalysts. The ZnO/PS heterostructures were studied by electron microscopy, and by photoluminescence ...
