Two monodisperse polystyrene microspheres, 2.76 and 9.25 μm in diameter, were prepared by dispersion polymerization in an ethanol/iso-propanol/water media. 2,2′-azobis(isobutyronitrile) (AIBN) and poly(acrylic acid) (PAA) were utilized as the initiator and steric stabilizer, respectively. Optical properties including total transmittance (T%) and transmittance haze (H%) were determined when these two monodisperse polystyrene microspheres were applied as diffusive agents. This paper mainly discusses (1) different particle-size effects and its hybrid behavior, (2) different thicknesses for the diffusion-layer effect, and (3) the effects of diffusion-layer arrangement and direction of incident light on the total transmittance (T%) and transmittance haze (H%).
