Webb12 jan. 2010 · The PL peak intensity rapidly increases even when only of alkaline-earth fluoride replaces MgO, probably because the impurity phase attributed to MgO decreases. The PL peak intensity increases with an increase in alkaline-earth fluoride content, but the increase rate strongly depends on the alkaline-earth element consisting of fluorides. WebbPL refers to exciting the sample at a fixed excitation wavelength and measure the corresponding emission from the sample with varying emission wavelength. In contrast, in PLE we fixed emission ...
