decaying curve in a sentence

1. Effective decay curves and articulation formula
2. Xrd patterns , excitation spectra , emission spectra , photo - stimulated emission spectra , photo - stimulated emission decay curves and thermo - luminescence spectra have been measured on the samples
3. The results indicated that the co - dopants of li + , na + and k + could promote the crystallinity of samples . however , the co - doping of mg2 + and al3 + drastically causes the structure disorder . ( 4 ) the fluorescence decay curves of 5do of samples were measured under the excitation of 266 nm laser
4. By the study of the whole decay curves of 10 hours , the influence of each step is summarized , and the best stoichiometry and preparation techniques are acquired . the crystal structure of sral2o4 eu2 + , dy3 + is monoclinic system , which is a high efficiency luminescence crystal structure . the emission spectrum and the excitation spectrum of sral2o4 eu2 + , dy3 + powder are measured
5. It's difficult to find decaying curve in a sentence.
