We also report the uv - visible optical absorption spectra of these colloids . to the metal plate prepared simultaneously , the measurement result of sem and afm of this plate is also reported and the roughness of the silver plate surface is about 60nm . both the colloids and the nano - scale metal surface can become the very perfect sers substrates . rhodamine b , a kind of strong fluorescence laser dye , with gold colloidal surface , has been studied by surface - enhanced raman spectroscopy ( sers ) with near - infrared ( nir ) excitation in the presence of the halide ions ( cf , br - , f ) 利用透射電子顯微鏡( tem ) ,對膠體粒子的尺寸大小及形態進行了觀測,表明這些膠體為粒徑介于5 35nm的納米體系,并對該膠體體系進行了紫外?可見吸收光譜的研究;在制備出金屬膠體的同時,經過激光照射后的金屬表面為納米量級的粗糙表面,對該表面進行了掃描電鏡( sem )及原子力顯微鏡( afm )的測量,結果顯示該表面的粗糙度平均為60nm 。

Meanwhile the photocatalytic performance of the films by using of rhodamine b as evaluation standards was studied . the results showed that in this experiment condition the optimal preparation condition for tio2 films which have better photoactivity was found to be : tio2 sol concentration 0 . 7mol / l , the amount of peg 0 . 5g , coating cycles 3 , heat - treated terms 480 c , ih 研究結果表明:在本實驗條件下,具有較好光催化活性的tio _ 2薄膜的最佳制備條件為: tio _ 2溶膠的濃度為0 . 7mol 1 ,聚乙二醇的加入量為0 . 5g ,鍍膜層數為3 ,熱處理溫度為480 ,保溫1h 。

A mixture of three amino acids ( arg , gly , glu ) labeled with fluorescein isothiocyanate ( fitc ) was separated in pdms microfluidic chip , the separation voltage is 200v / cm , the separation time is less than 120 seconds ; according to ccd fluorescence images , two distinct physical processes - stacking and destacking during sample injection were studied qualitatively ; rhodamine b , a kind of temperature - dependent fluorescence dye , was used as probe to develop a temperature - fluorescence intensity equation , then temperature - color map in microchannels was constructed , and temperature trait in microchannels on the pdms microfluidic chip was analysed . according to the results , we conclude that the electric field applied to the pdms microfluidic chip should not exceed 400v / cm 利用pdms微流控芯片對fitc標記的精氨酸、甘氨酸、谷氨酸混合物進行了電泳分離,分離電壓為200v cm ,分離時間不到120秒;通過拍到的熒光顯微圖像對電泳注樣過程中復雜的樣品分子積聚與解聚現象作定性的分析;以熒光染料rhodamineb為溫度熒光探針,建立了pdms微流控芯片上的溫度-熒光強度的關系公式,并利用matlab圖像處理工具箱構建出微流體溝道內的溫度色圖,對pdms微流控芯片的微流道溫度特性進行了分析,根據實驗結果,我們認為對于pdms微流控芯片來說,在進行需要外加電場作用的試驗時,外加電場不應超過400v cm 。

The influences of initiative concentration of rhodamine b , and the acidity of solution on the degradation rate of the tio2 films were discussed in the part of photodegradation of dye rhodamine b . the results indicated that the dye had the best photodegradation efficiency when the concentration of rhodamine b was 10mg / l and the acidity of solution was 3 研究了染料羅丹明b的初始濃度、溶液的酸度等因素對tio _ 2薄膜降解率的影響。結果表明,在本實驗條件下,當羅丹明b溶液的濃度為10mg l , ph = 3時,染料具有最佳的降解效果。
