A seed layer-assisted chemical bath deposition method performed at low temperature has been developed to grow uniform and high-quality crystal cuprous oxide (Cu₂O) nanoparticles on transparent conductive/glass substrates. The annealing process by continuous beam (CW) of CO₂ laser was used prior to growing the Cu₂O nanoparticles. In this study, the controlled synthesis of Cu₂O films was investigated by controlling the growth temperatures at 55 °C, 60 °C, 65 °C, and 70 °C, respectively. The modified seeding substrate reflect enhanced structural properties with laser annealing temperature of 450 ℃. In addition, Cu₂O nanoparticles with flower-like stricter show a greater density containing a smaller particle with 75 nm average dimension and flower particle size was about 85 nm. Results suggest an effective synthesis route for developing high-quality Cu₂O nanoparticles for optical and electronic applications.

已经开发了在低温下执行的种子层辅助化学浴沉积方法，以在透明导电/玻璃基板上生长均匀且高质量的晶体氧化亚铜（Cu ₂ O）纳米粒子。在生长Cu ₂ O纳米粒子之前，使用了通过连续光束（CW）进行的CO ₂激光退火工艺。在这项研究中，通过将生长温度分别控制在55°C，60°C，65°C和70°C来研究Cu ₂ O膜的可控合成。改性种子衬底在450℃的激光退火温度下具有增强的结构性能。另外，Cu ₂花状更严格的O纳米粒子显示出更大的密度，其中包含一个平均尺寸为75 nm的较小粒子，并且花的粒径约为85 nm。结果表明，开发用于光学和电子应用的高质量Cu ₂ O纳米粒子的有效合成途径。
