Abstract

Cloud structure and evolution of Mesoscale Convective Systems (MCSs) retrieved from the Tropical Rainfall Measuring Mission Microwave Imager (TRMM TMI) and Precipitation Radar (PR) were investigated and compared with some pioneer studies based on soundings and models over the northern South China Sea (SCS). The impacts of Convective Available Potential Energy (CAPE) and environmental vertical wind shear on MCSs were also explored. more...

Abstract

Red phosphors of Eu3+ and Bi3+ single-and double-doped LaMgB5O10 have been synthesized by a solid-state reaction.The red emission intensities were enhanced with the increase of Bi2O3 content.The crystal structures were analyzed using the X-ray diffraction.It indicated that the crystallization is better in the codoped samples than the Eu3+ monodoped sample.According to the results calculated by the Judd-Ofelt theory,the internal quantum efficiencies keep a constant value of about 43%.Moreover,red emission intensity increase 50% in the codoped sample comparison with the Eu3+ monodoped one under 394 nm excitation.It was confirmed that the enhanced red photoluminescence is due to the increase of Eu3+absorption strengths. more...
