We report multiple temperature effects on green and red up-conversion emissions in Er3+-Y b3+-Mo6+ codoped TiO2 phosphors. With increasing temperature, the decrease of the red emission from 4F9/2→4I15/2, the increase of green emission from 2H11/2

Position, Navigation, and Timing Technologies in the 21st Century
Radio waves such as the global navigation satellite system (GNSS) signals propagating through the ionosphere will experience varying levels of absorption, refraction, scattering, and polarization shift. The two remaining effects, refraction and scatt

Precise measurements of signal phase are essential for Global Navigation Satellite System (GNSS) position estimates. However, propagation through the earth's ionosphere imposes frequency-dependent phase errors. The frequency dependence is exploited t

Ionosphere scintillation can cause significant errors in global navigation satellite system (GNSS) phase measurements. During strong scintillation and, in particular, at low latitudes, diffraction causes deep fading in signal amplitude and rapid chan

This paper presents a physics-based, multifrequency, strong scintillation simulator that requires only two input parameters: the S4 index and decorrelation time t0. This simulator is developed based on the two-component power-law phase screen model,

Zinc oxide (ZnO) nanostructures have been widely used in biosensor applications. However, little attention has been given to the interaction of ZnO structures with physiological buffer solutions. In the present work, it is shown that the use of buffe
