A model for the wavelength/frequency of Hawking radiation emitted by non-spinning black holes in terms of the radius of event horizon ((lambda=8pi R_{s} ;&; v=c/8pi R_{s})) is proposed using quantum theory of radiation ( (E=hnu)), energy of Hawking radiation and the radius of event horizon of non-spinning black holes ( (R_{s}=2GM/c^{2})). This can be used as the characteristics of non-spinning black holes. Data for the frequencies and wavelengths of Hawking radiation emitted from black holes have been calculated with the help of rest masses for stellar-mass black holes (M~5-20 MO) in X-ray binaries and for the super massive black holes (M~ 106 – 109.5 MO) in active galactic nuclei using the model given by (lambda=8pi R_{s} ;&; v=c/8pi R_{s}) of the research work entitled: Frequency of Hawking radiation from black holes by Mahto et al.(Dec.2013). The astrophysical objects emitting the radiations of frequencies (8.092x102Hz to 2.023x102Hz) or wavelengths (3.707x105 m to 14.828x105m) in X-ray binaries and frequencies ( 4.046X10-3Hz to 0.809X10-6Hz) or wavelengths (7.414X1010m to 37.070X1013m) in active galactic nuclei may be classified as non-spinning black holes. These frequencies or wavelengths may be regarded as the characteristics of black holes in addition to the mass, spin and charge.

Dilepton emission is calculated from quark-gluon plasma (QGP) with the consideration of temperature dependent chemical potential (TDCP). The model is considered to be quasi-model and hence take the dynamical quark mass as a finite value dependence on temperature. The temperature in quark mass enhances in the growth of dilepton emission rates. The emission rate of dilepton spectrum is shown in the intermediate mass region (IMR) of 1.0 - 4.0 GeV and its rate is observed to be a strong increasing function of the temperature dependent chemical potential for quark and anti-quark annihilation.
