輻射變晶的
英文
metamict-
( 2 ) the index changes induced by cw laser at milliwatt in linbo3 : fe crystals are studied experimentally in detail. furthermore the experimental results are theoretically analyzed and numerically simulated. the results show that waveguide structures can be effectively induced employing structure light irradiation in linbo3 : fe crystals
在功率密度為毫瓦量級的連續激光輻照下，對linbo _ 3 ： fe晶體中的光致折射率變化規律進行了詳細的實驗研究，並對實驗結果進行了理論分析及數值模擬。Such control can be realized in case where a atom interact with photonic band gap matericals when the atom is placed in photonic crystals whose density of modes is dramatically different from that of free space vacuum. it was known that control could be achieved by varying the frequency ( which leads to the changes of the relative position of the upper levels from the forbidden gap ) or by varying the photonic density of modes ( dos ) or by varying the intial atomic state
由於光子晶體具有不同於真空中的光子態密度，原子和光子帶隙材料便發生相互作用，這樣便可以控制原子的自發輻射。改變原子上能級與光子禁帶邊緣的相對位置、材料中的光子態密度或原子初態都可以控制原子的自發輻射。The band was previously associated with f - type color centers and v - type color centers, as analyzed in x - ray irradiated ysz sample. however, the absorption band observed in our experiments has a shift towards the longer wavelength ( red shift ) as comparing with that in the x - ray or neutron irradiated ysz spectra. this shift may mainly due to large local distortions near the f - type centers and the v - type centers and the presence of multiple color centers
本文通過光吸收、光熒光、 tem 、 xps測試及trim96計算分別研究了不同注量xe ~ +注入ysz前後光學性能和缺陷形態變化，以及ni ~ +注入對不同摻雜單晶al _ 2o _ 3結構和光學性能的影響，得到以下結果： （ 1 ） ysz注量達到10 ~ （ 16 ） cm ~ （ - 2 ）時，開始出現由f型和v型色心重疊而產生的吸收帶，與x射線、中子輻照相比，重離子輻照產生了更為復雜的缺陷復合體而導致吸收峰紅移。It concluded that self - activated luminescent centers are not distributed randomly but prefer to occupy the surface sites in nanoparticles. 5. by raman spectra, epr spectra and uv irradiation - induced spectra change, the organic function groups of - oh, - ch3 and - coo adsorbed electrically on the surface of nanoparticles were discussed
Zns射漪屆劣結匆、齡腔與發芳碩里j筍應忿丈君漪扮5藉助raman光譜， epr （電子順磁共振）光譜以及紫外輻照誘導的光譜變化等實驗手段，較深入的研究了納米晶的表面態。Luminescence is caused by chemical, biochemical, or crystallographic changes, the motions of subatomic particles, or radiation - induced excitation of an atomic system
發冷光是由化學，生化或結晶變化，亞原子顆粒的運動，或原子系統的輻射產生的。But the absorption efficiency, stokes efficiency, quantum efficiency and the superposition efficiency between pump mode and cavity mode is less than one respectively, so the local heat absorption of the crystal is quite strong, and its thermal effect is quite obvious. two measures were taken
但是，由於量子效率小於1 ，斯托克斯頻移，泵浦光與基模的非完美空間重疊以及激光晶體的偏振吸收等因素積聚在晶體內的熱量隨泵浦輻射而變化，出現更為復雜和明顯的熱透鏡效應。In photorefractive crystal light illumination changes the refractive index of the crystal due to linear electrooptical effect, which in turn changes the light distribution. as a result of the development of this process, a beam, called the phase conjugation wave, leaves the crystal back along the direction of the incident beam and is its phase conjugate replica
光折變晶體在光輻照下，通過晶體中的線性電光效應而產生折射率隨光強的空間分佈而變化，即在晶體內建立起體相位柵。4 ) the thz resistivity of doped zn0. 95cd0. 05te < 110 > crystals changes with different doping following the similar way as the dc resistivity, which results in different thz wave generation efficiency
對于有摻雜的zn吧人內。 p 11o單晶，通過不同摻雜可以改變zn95cd ste叫單晶的電阻率，從而改變樣品產生thz輻射的效率。分享友人
