Embodiment 1
[0024] A method for preparing a red-light material based on Co-doped ZnO, the steps are as follows:
[0025] 1) Weigh 1.3g of zinc acetate and 0.04g of cobalt acetate, mix and dissolve in 60ml of absolute ethanol, and ultrasonically dissolve for 30 minutes;
[0026] 2) Weigh 1.6g of sodium hydroxide, dissolve it in 40ml of absolute ethanol, and ultrasonically dissolve it for 30 minutes;
[0027] 3) Pour the sodium hydroxide solution prepared in step 2 into the mixed solution of zinc acetate and cobalt acetate prepared in step 1, magnetically stir for 30 minutes, then pour the resulting mixed solution into a three-necked bottle, and put the three-necked bottle Put it into a water bath, connect the condensing tube to reflux, heat in a water bath at 90°C and magnetically stir for 2 hours, and finally centrifuge the solution;
[0028] 4) The separated precipitate was washed three times with deionized water and absolute ethanol respectively, and the precipitate was dried in a forc...
Embodiment 2
[0035] A method for preparing a red-light material based on Co-doped ZnO, the steps are as follows:
[0036] 1) Weigh 2.4g of zinc acetate and 0.028g of cobalt acetate, mix and dissolve in 110ml of absolute ethanol, and ultrasonically dissolve for 30 minutes;
[0037] 2) Weigh 2g of sodium hydroxide and dissolve it in 50ml of absolute ethanol, and ultrasonically dissolve it for 30 minutes;
[0038] 3) Pour the sodium hydroxide solution prepared in step 2 directly into the mixed solution of zinc acetate and cobalt acetate prepared in step 1 and stir it magnetically for 30 minutes, then place the resulting mixed solution in a water bath at 80° C. Stir and fully react for 2 hours, and finally centrifuge the solution;
[0039] 4) The separated precipitate was washed three times with deionized water and absolute ethanol respectively, and the precipitate was placed in a blast drying oven at 40° C. to dry to obtain a Co-doped ZnO luminescent material.

Embodiment 3
[0043] A method for preparing a red-light material based on Co-doped ZnO, the steps and process conditions are the same as in Example 1, except that the sodium hydroxide in step 2 is changed to potassium hydroxide of the same quality.
[0044] The luminescent properties of the Co-doped ZnO red light material prepared in this example are similar to those in Example 1.
[0045] The Co-doped ZnO material is used as an inorganic functional layer, the method is basically the same as in Example 1, the difference is that polyethylene glycol is used as a dispersant, and the Co-doped ZnO nanomaterial is dispersed in a polyethylene glycol solvent Co-doped ZnO polyethylene glycol solution was formed, and then the Co-doped ZnO polyethylene glycol solution was spin-coated on the zinc gallium oxide (GZO) transparent polyethylene plastic substrate that had been ultrasonically cleaned and dried. The GZO electrode is the anode of the device with a resistance of 20Ω / □; the silver-lithium alloy ...
