Summary:
With the infrared optical glass doped with rare earth elements in the defense, medical, aerospace, equipment and other areas increasingly popular, the optical identification of the finished material to measure material properties for the pros and cons as well as new materials to the development of ideas has played a decisive role. Spectral characteristics of optical materials as rare earth magnets a measure of symbolic means, the fluorescence emission spectra as well as for the detection of the fluorescence lifetime of research and improvement of test methods is particularly important.
In this paper, the semiconductor laser diode as a pump light source, optical company with Zhuoli Han grating monochromator and photodetector match, in the various test results of samples than the latter summarizes some of the tests can interfere with the measurement results of factors. At last, conclusions built for doped Nd ~ (3) and Yb ~ (3) ions of the http://www.chinamagnets.biz/ glass and powder samples of 800m-1500mn band fluorescence emission spectra and fluorescence lifetime measurement system. After comparison with the literature that use this system the measured data to be authentic.
