Ce3+ ion doped olgite mineral samples, Na(Sr, Ba)PO4, were prepared by a high temperature solid-state reaction. The sample was investigated through x-ray powder diffraction, FT-IR and FT-Raman spectra measurements. optical properties under vacuum ultraviolet (VUV) synchrotron radiation (UV) irradiation are reported for the first time. samples show strong absorption in VUV UV ranges. bands corresponding to 4f1 → 4f05d1 transitions of ions host lattices identified. barycentre lattices,...
Abstract High-quality ground observation networks are an important basis for scientific research. Here, automatic soil network high-resolution satellite applications in China (SONTE-China) was established to measure both pixel- and multilayer-based moisture temperature. SONTE-China is distributed across 17 field stations with a variety of ecosystems, covering dry wet zones. In this paper, the average root mean squared error (RMSE) station-based well-characterized sites 0.027 m 3 /m...
The samples on the base of substitutions Sr-cation in apatite Sr5(PO4)2(SiO4) were prepared by conventional solid-state reaction method: I) Sr4.75-5xCa5x(PO4)2(SiO4):Eu0.252+ (0.01 ≤ x 0.95) and II) Sr4.75-5yBa5y(PO4)2(SiO4):Eu0.252+ z 0.5). crystal phase formations investigated X-ray powder diffraction patterns. tunable green-yellow color was detected due to substitution cation Sr2+ host lattice either Ca2+ or Ba2+. relationship between structure luminescence properties reported....
Mildew of maize seeds may affect their germination rates and reduce crop quality. It is crucial to classify efficiently without destroying original structure. This study aimed establish hyperspectral datasets using imaging (HSI) with different degrees mildew then them spectral characteristics machine learning algorithms. Initially, the images were processed Otus morphological operations. Each seed's features extracted based on its coding, edge, region interest (ROI), pixel coding. Random...
A new blue-emitting phosphor based on calcium strontium phosphate host matrix, Ca2Sr(PO4)2:Eu2+, was prepared by solid state reaction. The X-ray powder diffraction, photoluminescence excitation and emission spectra, decay curves were measured. emits bright blue luminescence under the of near ultraviolet light. natures Eu2+ emission, e.g., Stokes shift, chromaticity, quenching temperature (T0.5) reported. It is identified that dipole–dipole interaction plays a major role in mechanism...
Wide mode SAR images have an apparent incidence angle effect. The existing incident normalization methods assume that the relationship between (θ) and backscattering coefficient (σPQ) does not change with growth stage of crops, which is in conflict real-life situation. Therefore, results σPQ based on these will affect accuracy object classification, target recognition, land surface parameter inversion. Here, θ-σPQ was investigated time-series (April to October) maize canopies northeast...
In order to reduce the impact of noise on accuracy inversion products based SAR images, many filtering algorithms have been developed for reduction images. This paper proposes a method spatial autocorrelation feature block fast Fourier transform (BFFT). The statistically analyses length speckle Sentinel-1B images different features and then constructs relationship between period. After that, size optimal FFT window radius was determined period components in image frequency domain. Finally,...
Soil moisture plays an important role in crop yield estimation, irrigation management, etc. Remote sensing technology has potential for large-scale and high spatial soil mapping. However, offline remote data processing is time-consuming resource-intensive, significantly hampers the efficiency timeliness of Due to high-speed computing capabilities cloud platforms, a High Spatial Resolution Moisture Estimation Framework (HSRSMEF) based on Google Earth Engine (GEE) platform was developed this...
Marius Hills volcanic complex (MHVC) comprises one of the densest structures on Moon and is significant interest for comprehending lunar volcanism.
