We present a spectroscopically complete sample of 147 infrared-color-selected AGN down to a 22 \mu m flux limit of 20 mJy over the \sim 270 deg ^ { 2 } of the SDSS Stripe 82 region .
Most of these sources are in the QSO luminosity regime ( L _ { bol } \gtrsim 10 ^ { 12 } L _ { \odot } ) and are found out to z \simeq 3 .
We classify the AGN into three types , finding : 57 blue , unobscured Type-1 ( broad-lined ) sources ; 69 obscured , Type-2 ( narrow-lined ) sources ; and 21 moderately-reddened Type-1 sources ( broad-lined and E ( B - V ) > 0.25 ) .
We study a subset of this sample in X-rays and analyze their obscuration to find that our spectroscopic classifications are in broad agreement with low , moderate , and large amounts of absorption for Type-1 , red Type-1 and Type-2 AGN , respectively .
We also investigate how their X-ray luminosities correlate with other known bolometric luminosity indicators such as [ \ion O3 ] line luminosity ( L _ { [ OIII ] } ) and infrared luminosity ( L _ { 6 \mu { m } } ) .
While the X-ray correlation with L _ { [ OIII ] } is consistent with previous findings , the most infrared-luminous sources appear to deviate from established relations such that they are either under-luminous in X-rays or over-luminous in the infrared .
Finally , we examine the luminosity function ( LF ) evolution of our sample , and by AGN type , in combination with the complementary , infrared-selected , AGN sample of , spanning over two orders of magnitude in luminosity .
We find that the two obscured populations evolve differently , with reddened Type-1 AGN dominating the obscured AGN fraction ( \sim 30 % ) for L _ { 5 \mu { m } } > 10 ^ { 45 } erg s ^ { -1 } , while the fraction of Type-2 AGN with L _ { 5 \mu { m } } < 10 ^ { 45 } erg s ^ { -1 } rises sharply from 40 % to 80 % of the overall AGN population .
