Disclosed herein is a polymeric film, the film comprising a polymeric matrix material, a plurality of perovskite nanocrystals and/or aggregates of perovskite nanocrystals dispersed throughout the polymeric matrix material. There is also disclosed a perovskite polymer resin composition, a perovskite-polymer resin composition, a perovskite ink and a method of forming a luminescent film using any one of the compositions or ink. Preferably, the perovskite material is a lead halide perovskite containing a cation selected from Cs, an alkylammonium ion, or a formamidinium ion. The polymeric matrix is preferably formed from monomers comprising a vinyl or an acrylate group.

A photocurable transparent ink composition for three-dimensional molding includes the following components in parts by weight: 60-125 parts of a photocuring agent, 0.01-5 parts of a yellowing adjusting agent, 0.5-5 parts of a photoinitiator, and 0.5-5 parts of an auxiliary agent, where the yellowing adjusting agent can absorb light in a wavelength range of 560 nm to 650 nm, so that the ink composition appears transparent. The photocurable transparent ink composition for three-dimensional molding can prevent yellowing of a printed article and make the printed article show a whiter, more transparent, and brighter appearance.
