Embodiments in accordance with the present invention encompass compositions encompassing a latent catalyst and a thermal or photoactivator along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is heated to a temperature from 50° C. to 100° C. or higher to form a substantially transparent film. Alternatively the compositions of this invention also undergo polymerization when subjected to suitable radiation. The monomers employed therein have a range of refractive index from 1.4 to 1.6 and thus these compositions can be tailored to form transparent films of varied refractive indices. The compositions of this invention further comprises inorganic nanoparticles which form transparent films and further increases the refractive indices of the compositions. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as coatings, encapsulants, fillers, leveling agents, among others.
