Original Abstract Submitted

An optical film includes an optically diffusive layer including a plurality of nanoparticles dispersed between and across opposing first and second major surfaces thereof. The plurality of nanoparticles has a nanoparticle size distribution including distinct first and second peaks at respective nanoparticle sizes d1 and d2, wherein 1.5≤d2/d1≤10. The optically diffusive layer includes a polymeric material bonding the nanoparticles to each other. For a substantially collimated substantially normally incident light, the optical film has, in a visible wavelength, an average specular transmittance VTs and an average total transmittance VTt, and in an infrared wavelength range, an average total transmittance ITt and an average specular transmittance ITs, wherein 0.3≤(VTs/VTt)≤0.7, (VTs/ITs)≤0.25, and (ITs/ITt)≥0.7.
