Özet
Optical behavior of greenhouse coatings based on Polyethylene terephthalate (PET) embedded with scattering (TiO2) and fluorescent pigments (K2SiF6:Mn4+) are investigated through numerical analysis. Effect of pigment effect on net photosynthesis of soybean at different pigment concentrations and latitudes are investigated. The study is carried out by numerical analysis and broadband radiative transfer of the fluorescent coating is modeled using the Monte Carlo method. It is found that neither fluorescent nor scattering pigments increase photosynthetic active radiation transmitted to greenhouse. However, plant growth increases at lower latitudes due to decreased stress by decreasing solar intensity. Moreover, using scattering (TiO2) pigments rather than fluorescent (K2SiF6:Mn4+) pigments is found to be also useful to decrease the stress.
