zinc blende 【礦物】閃鋅礦。

zinc galvanizing

However , it is not easy to incorporate large n concentration in gap due to the large differences in lattice structure ( gan belongs to wurtzite structure while gap zinc blende structure ) and in lattice constant ( ~ 20 % ) between gan and gap , which will lead to an extremely large miscibility gap 然而要在gap中實現高濃度的摻氮并不容易。這主要是由于gap和gan之間較大的物理特性的差異,特別是晶格結構和晶格常數的差異,使得gap和gan存在較大的可混溶性間隙,從而難以生長高質量的高摻氮的gap材料。

Various chemical strategies have been introduced to the system to affect the dynamics of reaction , and thus , to adjust the nucleation and growth process . by using appropriate complexing agents as controlling reagents and adjusting the reaction temperature , both morphologies ( nanorods and fractals ) and structural phases ( zinc blende or wurtzite structures ) of cdse nanocrystals can be easily controlled . a precipitate slow - release controlled method was designed in the synthesis of manganese selenides 在化學調控合成思想的指導下,運用已取得的調控合成的成功經驗,利用mnseo3沉淀緩釋放出mn2 +源和硒源,在調節反應溫度的基礎上,于同一反應體系成功地合成了mnse2和mnse的立方體和球形微米晶,實現了產物組成和維度的調控,并對它們的磁行為進行了研究。

Zn power , se power and diethylamine was used as the sources in this method and nanocrystal znse powders were synthesized at 225 . these powders have been identified as polycrystal znse with zinc blende structure by xrd . the size of particle is about 100nm ~ 200nm 采用zn粉和se粉為原料,以二乙胺為溶劑,在225下得到了znse粉末, xrd結果顯示其為znse多晶粉末,從tem照片可看出其顆粒的尺寸約為100nm 200nm 。

This film has been identified as polycrystal znse with zinc blende structure by xrd Xrd結果顯示該薄膜為立方閃鋅礦結構的znse多晶薄膜。
