选频光释光——特征波长光释光测定年龄的技术

Selected frequancy optical luminescence ——Characteristic wavelength optical luminescence dating

光释光是结晶固体的特征发光性质 ,不同固体在不同波长的激发光源作用下 ,释放出来的光子的波长也是不同的。介绍了一种利用矿物的特征光释光测定年龄的方法。首先是采用 BG1999光释光谱仪选定激发光源 ,确定释放光子的频率 ,再用矿物的特征光释光谱作年龄测定。利用这一技术获得的年龄数据不仅准确度高 ,而且可信度大。

A new technique of optical luminescence (OL) dating using the characteristic wavelength of a crystal is introduced. The spectra of optical luminescence of crystal are its luminescence character. The selected frequency optical luminescence dating (SFOLD) means that the characteristic frequency of the crystal is used to dating. Equipment BG1999 is created for optical luminescence. This equipment will be provided as a different frequency stimulating optical source . Spectra of luminescence of the crystal will be displayed in the screen. Therefore, you can determine which wavelength is a characteristic wavelength of the crystal chosen. Then, this characteristic wavelength of crystal has been using to do dating, which techique will be help you to obtain a more correct data and a really age for the sample.
