| 1. | The night side of the moon, also, under certain circumstance, shows some luminescence phenomena . 月面的夜区在某些情况下也会显出某种发光现象。 |
| 2. | Organic electroluminescence ( oel ) is light - emitting phenomenon arising from luminescent materials in which electricity is transformed into light when turned appropriate voltage on 有机电致发光( organicelectroluminescence , oel )是指发光材料在电场作用下,将电能直接转化为光能的一种发光现象。 |
| 3. | Photoluminescence of titanate sodium nanotubes can be stable under humid conditions . 2 . nanotube titanic acid was surface - modified by 1 - hexadecanol , then its photoluminescence ( pl ) property was studied 纳米管钛酸钠在水气氛下长期放置后,荧光光谱没有变化,说明这种发光现象能够稳定存在。 |
| 4. | Our experiment results showed that the photoluminescence mechanism of porous silicon was ascribed to the co - effect of quantum confinement and the surface materials of porous silicon 以上的多孔硅发光现象不能用单纯的量子限域机制进行解释,实验结果表明它是由量子限域和多孔硅表面物质共同作用的结果。 |
| 5. | The ti - o - ch2 ( ch2 ) 14ch3 at the surface of nanotube exhibited a good resistance to adsorption of water and the stable pl was obtained . we also studied the photoluminescence of titanic acid nanotubes under liquid nitrogen condition 修饰层的存在能够有效抑制纳米管钛酸对水的吸附,较好的保持纳米管钛酸特殊的发光现象。 |
| 6. | The photoluminescence was not found in the samples of yl1 and bl3 which are 2000pa of 50 % o2 and 50 % ar , 4000pa of 60 % o2 and 40 % at temperature 800 because of impurities and vacancies which eliminate the excitons Yl1和bl3试样没有出现发光现象,主要是由于这两个试样中都存在纯锌相,杂质和空位较多,降低了激子的寿命。 |
| 7. | Luminance : project light upon in the ultraviolet ray wave under have thin huang green arrive blue fluorescence , short - wave fluorescence not obvious , the x shoots line irradiation to descend also have no give out light phenomenon obviously 发光性:在紫外线波照射下有淡黄绿到蓝色的荧光,短波荧光不明显, x射线照射下也无明显的发光现象。 |
| 8. | 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 三根据pl谱,分析了si一510 :薄膜样品的室温光致发光现象,样品有一320 ,翻,一410nm ,一56onm和一630nm四个pl峰,它们的pl峰是相互分离的。 |
| 9. | The photoluminescence of the thin films without post heating shows that the increasing of the deposit temperature decreases the pl intensity . only the sample deposited at 450 has one evident luminescence band found nearby 523 . 2nm 对复合镶嵌薄膜光致发光特性的研究发现,在450沉积未经过退火处理的薄膜样品中观察到室温光致发光现象,在523 . 2nm附近有一强的发光谱带。 |
| 10. | The photoluminescence of the thin films without post heating is weak . only one luminescence band is found nearby 473nm . two luminescence bands are found after post heating , nearby 493nm and 368nm respectively . the intensity of the luminescence bands increase little by little when the temperature and the time of post heating continues to increase 而退火处理过后,薄膜出现两种光致发光现象,即蓝色发光和紫外发光,其峰值分别在493nm和368nm附近,而且随着退火温度的升高和退火时间的延长,发光谱带的强度逐渐增大,峰形的位置也有不明显的蓝移。 |
