The commercial application of colloidal semiconductor nanocrystals has been realized owing to the development of composite film technology. Here, we demonstrated the fabrication of green and red emissive CuInS2 nanocrystals embedded polymer composite films of equal thickness by using a precise solution casting method. The impacts of polymer molecular weight on the dispersibility of CuInS2 nanocrystals were then systematically studied through evaluating the decrease in transmittance and red shift of emission wavelength. The composite films made from PMMA of small molecular weights exhibited higher transmittance. Applications of these green and red emissive composite films as color converters in remote-type light-emitting devices were further demonstrated.

With the rapid development of the current power supply enterprise, it is necessary to process the distribution network business according to the actual business requirements, and easily collect and transfer the archiving and operation data in four distribution network equipment types from the source business system to explore the potential correlation of power big data indicators. This paper proposes one method of constructing the distribution network operation monitoring index system based on two aspects of operation efficiency and power supply capacity, and proposes a corresponding data analysis model for detailed analysis, and finally carries out the model verification. The experimental tests of four types of equipment operation analysis in the internal big data distribution network show that, the proposed methods could locate the distribution network operation quickly and accurately.
