Abstract: The present invention relates to a Cu2Zn0.14Sn0.25Te2.34 nanocrystalline solution, its preparation method, a photosensitive resin solution, a method for forming black matrixes (BMs), and a color filter (CF) substrate. As the particle size of nanocrystallines in the nanocrystalline solution is small and light within the ultraviolet-visible light range can be absorbed, the BMs formed by utilization of the nanocrystalline solution can obtain good light shielding performance while having a small thickness. In the nanocrystalline solution, the particle size of the nanocrystallines dispersed in the nanocrystalline solution is 5 to 20 nm; the band gap of the nanocrystallines is 0.8 to 1.5 ev, and the grain surface of the nanocrystallines has organic functional groups.
