Abstract BaAl 12 O 19 : Mn 2+ doped with Mg 2+ , Sr 2+ and La 3+ cations and BaMgAl 10 O 17 : Eu 2+ doped with Ca 2+ and Sr 2+ cations were synthesized by the high temperature solid state reaction method. The crystal structures and luminescent properties of these phosphors have been studied by XRD and luminescent spectra especially excited by vacuum ultraviolet.

Preparation of High-Thickness n−-Ga2O3 Film by MOCVD

Coatings (2022)

Chunlei Zhao Teng Jiao Wei Chen Zeming Li Xinyong Dong

The homoepitaxial Si-doped Ga2O3 film prepared by metal–organic chemical vapor deposition (MOCVD) was reported in this paper. The film thickness reached 4.5 microns, a relatively high value for MOCVD. The full width at half maxima of the (002) diffraction plane of the film was 26.3 arcsec, thus showing high crystalline quality. The film showed n−-type properties with a doping concentration of 3.6 × 1016 cm−3 and electron mobility of 137 cm2/V·s. In addition, the element composition and stress state of the film were characterized and analyzed. This indicates that the MOCVD, supporting high-quality, high-precision epitaxy, is promising for Ga2O3 power devices.

Polarization radar target recognition based on optimal curve fitting

Huamin Tao Jianjun Yin Chunlei Zhao

In this paper, the conception of VOPS (Velocity of Polarization State) is presented to describe the dynamic characteristics of radar target's polarization structure in the frequency domain an the polarimetric and high-resolution radar system. An improved simulated annealing method is presented to estimate the global optimal parameters of fitting curves of target's dynamic distributions. Furthermore, recognition experiment has been made on four kinds of aircraft and good results are achieved.
