Examples
- Fwhm full width at half maximum
电平全带宽半最大值处全带宽 - For the first time , we obtain a ( 002 ) orientated high quality zno thin films with the full width at half maximum ( fwhm ) of 0 . 2o located at 34 . 42o at a low temperature of 180
首次报道了用这种方法在衬底温度为180oc条件下制备了（ 0002 ）择优取向，其x -射线衍射峰的半峰宽为0 . 2度的高质量氧化锌薄膜。 - The relationships between the substrate temperature and the properties of zno films were studied in detail , we obtained a ( 002 ) orientated high quality zno thin films with the full width at half maximum ( fwhm ) of 0
用这种方法在衬底温度为180条件下制备了( 0002 )择优取向， x -射线衍射峰的半高宽为0 . 2度的高质量氧化锌薄膜。 - When the time of heat preservation prolonged , the intensity of most orientation of perovskite phase became stronger , and the full width at half maximum ( fwhm ) decreased . when the time of heat preservation was 80 seconds , the intensity of ( 100 ) and ( 110 ) orientation began to decrease
循环次数从1次增加到3次, plt薄膜的( 100 )和( 200 )峰的衍射强度逐渐增强,薄膜的结晶性提高,铁电性能逐渐增强,循环4次溅射后,薄膜的结晶性和铁电性开始下降。 - ( 2 ) several samples of different structure parameters are grown by low - pressure metal - organic chemical vapor deposition ( lp - mocvd ) . it is found that pl peak intensity , full width at half maximum ( fwhm ) and light output intensity are greatly dependent on number of wells . ratio of well / barrier width nearly has no effect on pl peak intensity and fwhm , but has little relation to light output intensity
通过分析pls ，可以及时获取材料生长和结构设计的数据，对质量控制有重要的指导意义； ( 2 )对不同结构的gainp algainp多量子阱样品进行了光致发光及出光强度的测量，发现mqw的周期数目n对pl峰强度、半峰宽和出光强度的影响最大；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。
