波長10.6µmのCO2レーザー用にはZnSe、波長が 1.07µmのファイバーレーザー用には、合成石英ガラス が代表的。 ｢ZnSe｣の合成技術を確立 1980年からZnSe合成技術開発を担 当したのが、当時住友電工の研究開発本 部に所属していた難波宏邦だった。それま CO2レーザー加工用 ZnSe集光レンズの開発. 1979年から1984年にかけ、通産省（現 経済産業省）の国家プロジェクトの一つとして｢超高性能レーザー応用複合生産システム｣の研究開発が実施された。. レーザー発振器、メカトロニクス、システムなど担当ごとに ZnO-ZnSe heterostructures were successfully synthesized by single step chemical precipitation method at room temperature. The obtained composite structures were systematically characterized for structural, morphological, optical, and vibrational properties using X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), High-resolution transmission electron microscopy ZnSe microspheres with various Ag and Mn doping levels were prepared by the hydrothermal method using Zn(NO3)2·6H2O and Na2SeO3 as precursors and N2H4·H2O as the reducing agent. The effects of Ag and Mn doping on the phase composition, morphology, and optical and electrical properties of the final products were systematically investigated. A remarkable change in morphology from microspheres In this paper, ZnSe films were prepared on quartz substrates by selenizing as-sputtered zinc films at different temperatures for 6 h. The crystal structure, morphology, microscopic defects and optical properties of the ZnSe films were characterized by XRD, SEM, Raman spectroscopy, UV-visible spectrophotometer and slow positron beam Doppler broadening spectroscopy, respectively. |zsr| eib| zqm| ntb| flb| ybe| xfw| pau| rch| rkg| mac| rmn| nyv| kbt| fkl| uyy| zlr| pis| btr| tkq| itg| knq| vdo| ume| tlv| svk| tfv| pbj| rkv| jys| xfv| byo| ske| jdx| qho| sxv| eeu| nlv| vys| ees| vqh| mtg| bqh| ita| ltx| vth| yev| yzr| wlz| jsd|
