The process of cld-sio2 films is first studied in detail following houng et al .'s work 首先,我們先仔細(xì)研究了化學(xué)液相淀積氧化硅薄膜的過程(主要是參考houng等人的工作)。
It was found that the thickness of the film can improved with adding some mucilage glue . a low temperature sinter can acquire a transparent sio2 film on the gold electrode 增粘劑的加入可提高一次涂膜的厚度,低溫?zé)Y(jié)可在金電極上得到表面光亮的二氧化硅玻璃薄膜,絕緣性能良好。
The sims, ir and raman analysis results show that the tritium permeation barrier ( tpb ) is formed when tic and sio2 films are annealed in hydrogen at about 350 ? 利用二次離子質(zhì)譜(sims)、紅外吸收光譜(ir)及激光喇曼光譜(raman)技術(shù),證實了tic和sio2在350左右的氫中退火可形成防氚滲透阻擋層。
Xps results confirm the formation of sio2 . xrd results show that deposited sio2 films are amorphous . heat treatments explain that films are still amorphous as the temperature of heat treatment reach 800 xrd分析結(jié)果表明,所制備的sio_2薄膜結(jié)構(gòu)為非晶態(tài);在800以下退火,薄膜的結(jié)構(gòu)沒有發(fā)生明顯的改變,仍為非晶態(tài)。
The results of design explain that if sio2 films deposited on the surfaces of sapphire the average transmittance in 3 ~ 5 m waveband can exceed 97 %, which can meet the requirements of missile dome in infrared application 設(shè)計結(jié)果表明,藍(lán)寶石襯底雙面鍍sio_2、sio_2/si等膜系,在35m波段的平均透過率大于97,可滿足導(dǎo)彈頭罩設(shè)計和使用的要求。
3 . the pl results of si-sio2 films show that emission spectra of samples have 4 luminescent band peak at 320nm, 410nm, 560nm, and630nm, respectively, at room temperature, ta, the excitation wavelength, argon pressure et al 三根據(jù)pl譜,分析了si一510:薄膜樣品的室溫光致發(fā)光現(xiàn)象,樣品有一320,翻,一410nm,一56onm和一630nm四個pl峰,它們的pl峰是相互分離的。
Quantum confinement effect was observed in the films by measurements of absorption spectrum of ge-sio2 films . the widening of optical band gap of the amorphous films seems to be related to the function of the quantum confinement on the impurities or defects in the films 光吸收特性研究表明,因量子限域效應(yīng),對于ge-sio_2薄膜觀察到較強的光吸收和光吸收邊隨ge顆粒尺寸變小而藍(lán)移的現(xiàn)象。
