研究目的
Investigating the feasibility of waste collection and recycling in traditional evaporation deposition systems for the production of selenium nanoparticles.
研究成果
The study successfully demonstrated the recovery of selenium nanoparticles from waste materials in evaporation deposition systems. The method is useful for recycling costly or harmful materials, contributing to environmental protection and material sustainability.
研究不足
The study focuses on selenium and may not be directly applicable to other materials without further research. The efficiency of waste collection and the quality of recycled nanoparticles may vary with different materials and systems.
1：Experimental Design and Method Selection:
The study used thermal vacuum evaporation and evaporation assisted by Nd:YAG pulse laser systems to prepare selenium thin films.
2：Sample Selection and Data Sources:
Selenium pellets (
3：99% purity) were used to fabricate thin films. List of Experimental Equipment and Materials:
Equipment included a thermal vacuum evaporation system (EDWARDS with Mo-boat), Nd:YAG pulse laser system, ultrasound technology (Hielscher), and a vacuum furnace (IVOCLAR).
4：Experimental Procedures and Operational Workflow:
Thin films were prepared, waste materials were collected, rinsed, dried, and annealed.
5：Data Analysis Methods:
Particle size analysis, XRD, SEM, and AFM were used to characterize the materials.
