The europium complexes have an efficiency high PL, the monochrome red light and so on, making it be EL materials in application. 在发光材料方面,铕的配合物以其独特的发光特性使其在电致发光材料方面具有诱人的应用前景。
The products of ZnO and ZnS possess excellent photoluminescence ( PL ) property with a broad green light emission, and the ZnO have a UV light emission band ( 380 nm ), additionally. 光致发光(PL)表征表明所制备的氧化锌、硫化锌纳米材料都具有良好的绿光发射性能,同时氧化锌纳米材料还具有380nm的紫外光发射带。
With the aid of PLE spectra and the dependence of PL on the annealing temperature, the possible mechanism of light emission has been discussed. 结合光致发光(PL)激发谱(PLE)和薄膜结构以及退火对发光峰位影响方面的分析,对其可能的发光机理进行了初步的探讨。
The PL spectra of the film showed strong emission in the blue light band. 所得到的ZnO薄膜在蓝光波段具有强烈的受激发射。
Ratio of well / barrier width nearly has no effect on PL peak intensity and FWHM, but has little relation to light output intensity. 阱/垒宽厚度比a对PL峰强度和半峰宽的影响较小,但对发光强度的影响较大。
