##### Abstract:
Prominences are an inherent component of the solar corona. They are significantly cooler than the surrounding corona, indicating that they are thermally isolated. Therefore the prominence-corona transition region (PCTR) plays an important role to establish an equilibrium system comprising prominences and the ambient corona. We present a study on solar prominences, PCTR and the quiet Sun using the SDO/AIA observations. The intensity profiles of different spectral lines show that there is {\bf an intrinsic} temperature variation inside prominences. We then examine the temperature and density properties of prominences, PCTR and the quiet Sun by using the differential emission measure(DEM) analysis whereby the six-passband EUV observations are employed. Our DEM analysis shows that the temperature of the PCTR varies from logT6.0$\log T \sim 6.0$ to logT6.2$\log T \sim 6.2$.
