Abstract : Out of a large number of novae discovered, only a few (about 20%-25%) have been found to form dust in the ejecta. Study of such novae are of important to understand dust formation process and the physical parameters of the dust forming nova. V1280 Sco (2007) is such a nova that formed optically thick dust. Here we present the results of photoionization modeling of the spectra of V1280 Sco. We used the photoionization code CLOUDY c17.00 for modeling observed optical and near-IR spectra. We generated several spectra by varying associated parameters; the best-fit spectra was chosen by minimization technique. From the best fit model, we estimated various parameters, viz., the temperature and luminosity of the central hot white dwarf, elemental abundances etc. From model output spectra, we also identified the spectral features in more details.
