摘要：

We explore the diagnostic diagram that uses the ratio of emission lines ([NII]lambda 6584 angstrom/H alpha) versus equivalent width of [NII]lambda 6584 angstrom, proposed by Coziol et al. (1998) to a sample obtained from Sloan Digital Sky Survey Data Release 5 to separate star-forming and active galaxies from low-luminosity AGNs. This diagnostic diagram does not need the classical emission lines like [OIII]lambda 5007 angstrom, or H beta to classify activity type. We show empirically that this combination of emission lines can be used to search the called Low-Luminosity AGN.
