Pickering emulsions with a remarkable transmittance of up to 86% across the visible spectrum have been prepared without adjusting the refractive index (RI) of the stabilizing particles to those of the aqueous and oil phases. Commercially available hydrophilic silica particles with a diameter of 20 nm, which are hydrophobized partially in situ, were used to stabilize water droplets with diameters below 400 nm in IsoparM. In this system, the stabilizing particles and the emulsion droplets act as one single scattering object, which renders RI-matching of the particles unnecessary. By either evaporation of some water from the droplets or addition of an appropriate organic liquid to the oil phase, it is possible to match the RI of the droplets (aqueous phase + particles) with that of the continuous phase, which minimizes scattering and results in highly transparent emulsions.

高度透明的不带Picker乳液，无需调节稳定颗粒的折射率
已经制备了在可见光谱范围内具有高达86％的显着透射率的Pickering乳液，而没有将稳定颗粒的折射率（RI）调节为水相和油相的折射率。部分在原位疏水化的直径为20 nm的可商购亲水性二氧化硅颗粒用于在IsoparM中稳定直径小于400 nm的水滴。在该系统中，稳定颗粒和乳液液滴充当一个单一的散射物体，这使得颗粒的RI匹配变得不必要。通过从液滴中蒸发一些水或向油相中添加适当的有机液体，可以使液滴（水相+颗粒）的RI与连续相的RI相匹配，
