Preparation of Undoped LaCl3 Crystal and Its Luminescence Properties Ren Guohao1,Pei Yu1,Qin Laishun1,Chen Xiaofeng1,Li Zhongbo1 (1.Shanghai Institute of Ceramics, Chinese Academy of Sciences, Shanghai 201800, China) Abstract:In this paper, undoped LaCl3 crystal growth was reported by modified Bridgman method.The starting materials used as charge for crystal growth was found to contain seven......
. An increase in the high-temperature hydrolysis time results in the evolution of particle shapes from cube to quasi-sphere, and then to octahedron. The effect of NaCl additive on the surface morphologies... particles effectively. Key words: Co3O4; crystal structure; hydrolysis; surface morphology 1 Introduction Co3O4 is an important functional material and has been widely studied for applications......
J. Cent. South Univ. (2017) 24: 1826-1836 DOI: https://doi.org/10.1007/s11771-017-3591-9 A novel SMC-PHD filter based on particle compensation XU Cong-an(徐从安)1, HE You(何友)1, YANG Fu-cheng(杨富程)1, 2..., the particle impoverishment problem introduced by the resampling step, together with the high computational burden problem, may lead to performance degradation and restrain the use of SMC-PHD filter......
