SCI論文中描述XRD結(jié)果之Part 2. XRD定性分析物質(zhì)結(jié)晶程度和純度
1. 列舉型(推薦)
實(shí)例一:The diffraction pattern for the electrodeposited film has seven broadpeaks at11.8°, 16.8°, 26.7°, 35.2°, 39.2° , 46.4° and 55.9°, corresponding to(100), (200), (310),(211), (301), (411), and (521)of β-FeOOH (ICSD 31136),respectively.
(Ref.: Zou, S. etc., Chem. Mater.2015, 27, 8011 – 8020)
句式模板: ... shows/has/exhibits N(特征峰數(shù)目) peaks at _, _, _and _,corresponding to (), (), () and () of __ (JCPDS (或ICSD) ___), respectively.
變型: Wide-angle X-ray diffraction (WAXD) shows broadpeaksat _, _, and _°, which arecharacteristic of ... (JCPDS __).
優(yōu)點(diǎn):證據(jù)確鑿,內(nèi)容充實(shí),既讓人信服,又可以為下文的其他表征(比如高分辨電鏡中的晶面間距)打好基礎(chǔ)。
適合于:1) XRD結(jié)果或者物質(zhì)的晶型結(jié)構(gòu)對(duì)于文章主體內(nèi)容有重要價(jià)值的時(shí)候(例如,材料的晶型是重點(diǎn)考察對(duì)象(晶型影響材料性能)時(shí);必須通過(guò)XRD來(lái)對(duì)物質(zhì)組成結(jié)構(gòu)進(jìn)行定性時(shí));
2)下文其它表征需要和XRD結(jié)果進(jìn)行呼應(yīng)時(shí),比如HRTEM圖片中的晶面間距要和XRD (h,k,l)面進(jìn)行對(duì)應(yīng)時(shí);
3)有多個(gè)XRD譜圖需要描述時(shí),第一個(gè)譜圖的描述宜詳寫(xiě),這樣后面的譜圖描述就可以簡(jiǎn)略一些,詳略得當(dāng)。
2. 指派型
實(shí)例二:Peaks appearing in the original CdS rods can beindexed to wurtziteCdS (JCPDS __) and those in the fully exchanged rods can be indexed toacanthite (JCPDS __).
(Ref. : Robinson, R. etc., Science 2007, 317, 355-358)
句式模板:Peaks appearing in __ can be (well) indexed to __ (JCPDS __).
變型:The pattern for __ has a number of peaks that can be well-indexed to __(JCPDS __).
優(yōu)點(diǎn):言簡(jiǎn)意賅,直截了當(dāng)將譜圖指派給某一物質(zhì)。
適用于:1)材料組成簡(jiǎn)單且比較明確的情況下,XRD譜圖只是用來(lái)區(qū)別物質(zhì)組成時(shí);2)前文已經(jīng)有對(duì)其他XRD譜圖進(jìn)行具體描述時(shí),為了讓文章不重復(fù)啰嗦時(shí)。
3. 驗(yàn)證型
實(shí)例三:The crystal phase of CuO spheres was further confirmed byX-raydiffraction.
(Ref.: Zhu, J. etc., Energy Environ. Sci., 2013,6, 987-993)
句式模板:The crystal phase of __ was further confirmed byX-ray diffraction.
變型:We further confirmed that thepolycrystalline __ (spheres, nanoparticles,rods) belong to __ by XRD.
優(yōu)點(diǎn):句式極其簡(jiǎn)單
適用于:XRD結(jié)果作為輔助信息來(lái)驗(yàn)證前文已經(jīng)較為明確的結(jié)果時(shí)。
本文轉(zhuǎn)自研之成理
