Embodiment 1
[0037] Inorganic nano-CuInS is selected as fluorescent material 2 (CIS) quantum dots, the required CIS quantum dots are synthesized through the "one-pot reaction method". The outer layer of the CIS quantum dots is covered with a layer of ZnS. Absorbed blue-violet light is converted to broadband red-orange light emission. The synthesized CIS quantum dots are dispersed in n-hexane solution for use, and its characteristic spectrum is as follows figure 1 As shown, a is the absorption spectrum, b is the emission spectrum, and the wavelength difference between the excitation wavelength and the emission wavelength is greater than 180nm.
[0038] The planar optical waveguide is made by bulk polymerization of methyl methacrylate. The specific polymerization process is as follows:
[0039] Measure 20mL of the bulk solution of methyl methacrylate in a conical flask, weigh the white solid of azobisisobutyronitrile and add it to the bulk solution of methyl methacrylate, stir it evenly wi...
