顯藍退火 的英文怎麼說
中文拼音 [xiǎnlatuìhuǒ]
顯藍退火
英文
blue annealing-
The effect of deposited condition, include substrate temperatures, different substrates and annealing on the structural properties of zno films has been studied in considerable detail. it is found that the optimal conditions to deposit zno are below : the substrate temperature of 450c, the substrate of sapphire. the sample on this condition is 0. 3491
通過分析襯底溫度、不同襯底和退火對樣品結構的影響,得到了樣品的最佳制備條件:襯底溫度450 、藍寶石襯底,此條件下制備的樣品具有高度( 002 )取向性, ( 002 )衍射峰半高寬僅僅0 . 3491 ,原子力顯微鏡( afm )分析表明zno薄膜具有密集堆積的均勻柱狀晶粒。The photoluminescence of the thin films without post heating is weak. only one luminescence band is found nearby 473nm. two luminescence bands are found after post heating, nearby 493nm and 368nm respectively. the intensity of the luminescence bands increase little by little when the temperature and the time of post heating continues to increase
而退火處理過后,薄膜出現兩種光致發光現象,即藍色發光和紫外發光,其峰值分別在493nm和368nm附近,而且隨著退火溫度的升高和退火時間的延長,發光譜帶的強度逐漸增大,峰形的位置也有不明顯的藍移。
