Problems solved by technology

[0004] Compared with other semiconductor nanomaterials and solid solution thin film materials, the preparation of nanoscale multi-component solid solution nanowires is very difficult
Although there are a few reports on ZnSe-GaP solid solutions, most of them exist in the form of thin film bulk materials.
One-dimensional ZnSe-GaP solid solution nanowires have not been reported so far

Embodiment 1

[0029] The present embodiment ZnSe-GaP solid solution nanomaterial is prepared by the following process:

[0030] 1. Weigh a certain mass of zinc selenide and gallium phosphide powder (any molar ratio is acceptable), and place them in two porcelain boats respectively. Then weigh a small amount of zinc powder and selenium powder according to a molar ratio of 1:1, and the molar ratio of the two to the zinc selenide powder is 1:10, and put them in a porcelain boat filled with zinc selenide and mix them evenly.

[0031] 2. According to Figure 4 Arrangement method Put the two porcelain boats in step 1 into two small quartz tubes respectively, and put the two small quartz tubes into the large quartz tube together, and place the three quartz tubes in parallel with the nozzles in the same direction. Put the large quartz tube into the three-temperature-zone tube furnace, adjust the position of the porcelain boat, so that the porcelain boat with gallium phosphide is placed in the heat...

Embodiment 2

[0038] The present embodiment ZnSe-GaP solid solution nanomaterial is prepared according to the following steps:

[0039]1. Weigh a certain mass of zinc selenide and gallium phosphide powder (any molar ratio is acceptable), and place them in two porcelain boats respectively. Take zinc powder and selenium powder again, the mol ratio of zinc powder and selenium powder is 5:1, and the mol ratio of selenium powder and zinc selenide powder is 3:10, put in the porcelain boat that holds zinc selenide and mix uniform.

[0040] 2. Put the two porcelain boats in step 1 into two small quartz tubes respectively, and put the two small quartz tubes into the large quartz tube together, and place the three quartz tubes in parallel with the nozzles in the same direction. Put the quartz tube into the three-temperature zone tube furnace, adjust the position of the porcelain boat, so that the porcelain boat with gallium phosphide is in the heating center of the middle temperature zone of the tub...
