no not phosphorescent phosphorescence as far as i know does not occur in gases if you check the wiki article it refers to the delay in re emission characteristic of phosphorescence being associated with forbidden energy state transitions in quantum mechanics these transitions can only occur in solid materials the ir absorption emission associated with the so called greenhouse gases is due to molecular vibrations that are directly related to the molecular temperature phosphorescence is not particularly dependent on temperature whereas the absorption emission of ghgs is an exact function of the temperature of the molecule
