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。 |
