In the third chapter, the influence of current density, solution concentration, erosion time and aging in ambient air on the pl spectra of ps suggests that peak would blue shift with current density increasing, and with erosion time and aging time prolonging ; with the increasing of solution concentration, peaks would red shift when solution concentration less than 1 : 1 but blue shift when solution concentration greater than 1 : 1. above phenomena can be explained by quantum confinement and light center model, but do not deny the action of si - h bonding and defect on the surface in the process of photoluminescence. at present, radiation mechanism is still one of the primary problems in the study of ps
在第z三章中;通過對比,分析了電流密度、陽極化時間、溶液濃度以及自i然氧化時間對多孔硅光致發光光譜的影響,認為在一定的范圍內,多i孔硅的發光峰位會隨電流密度的增大而藍移,要獲得較強的發光,需z要選擇合適的電流密度;隨著腐蝕時間的延長,多孔硅的發光峰位會i發生藍移;當f酸的濃度較小q : 1 )時,峰位隨濃度的增大表現為向i低能移動;而當f酸的濃度較大河山時,峰位隨濃度的增大則表現z為移向高能;多孔硅在空氣中自然氧化;其發光峰位發生藍移,而強i度隨放置時間的延長而降低。Results showed : ( 1 ) cbt cell death in low tempratures is accompanied by characteristic changes, such as, reduced cell size, distorted nucleus, chromatin condensation and margination and cell ( cytoplasmic ) vacuolization ; cell mortality and ca2 * concentration increase along with time passed in low temperature. mitochondrial membrane potential and 02 increased at first, and then decreased. activities of sod decreased at first, followed by significant increasing and finally depressed
結果表明: ( 1 ) cbt在低溫協迫下,細胞圓縮,細胞核變形,染色質濃縮且邊位,細胞質空泡狀;細胞死亡率隨處理時間的增加而增加;細胞內鈣離子濃度隨處理時間延長而遞增;線粒體膜電位差在低溫處理早期急速上升,隨后一直下降;細胞內超氧陰離子( o _ 2 ~ - )在低溫處理前期出現高峰,接著呈下降趨勢;細胞內sod活性在低溫處理前期減弱,接著上升,然後持續下降。Compared the average value of experimental group with that of the control, when fed with water containing low concentration of lead, we got longer memory maintaining time in experimental groups than the control during the first few trainings and shorter time when fed with water containing high concentration of lead
訓練後期低濃度組與高濃度組記憶保持時間均低於正常組。討論正常對照組小鼠腦細胞漿pkc活性在pi至ps期間增加較緩,而在ps至n段迅速增加,並達到高峰,從n至p22段又明顯降低n為低谷,而後p30又升高。We researched the influences of systhesis temperature, heat preservation time, eu + concentration, reduction surrounding feeling and flux on luminescent properties of sral2o4 : eu2 + phosphors, optimized the experiment conditions and reduced systhesis temperature about 100 c. we found that the systhesized sample ' s luminescent brightness is better with increasing systhesis temperature, but the phase component is more complex. we found that the luminescence brightness of sample appear a increasing process at first, and then a reducing one with the raise of eu2 + concentration, it indicated that the luminescence brightness is not better if the eu2 + concentration is too high or low. we found that the systhesized sample can not bright at too long heat preservation time, and the luminescence brightness is lower at too short heat preservation time. we found that particle diameter is bigger, the wavelength of emission peak is longer
研究發現合成溫度高,合成樣品的發光效果好,但物相組成也較復雜; eu ~ ( 2 + )離子在一定摻雜濃度范圍內,合成樣品的發光亮度先是出現一個提高過程,然後是一個降低過程,說明eu ~ ( 2 + )離子濃度高或低都不利於合成樣品發光;保溫時間較長,合成樣品不發光,保溫時間較短,合成樣品發光效果不好,只有合適的保溫時間才能合成發光效果好的樣品;合成樣品的粒徑大小與發射峰的位置具有一定的關系,粒徑越大,發射峰越偏向長波方向;助熔劑對樣品的合成溫度和發光性能都有影響,助熔劑的量較低時,主要表現為助熔作用,對發光影響不大,助熔劑的量較高時,使得樣品發光亮度降低和余輝時間縮短;還原方式的不同,合成樣品的發光性能也不一樣。分享友人
