摘要
目的比较4种粒径纳米氧化锌粉末显现指印的效果。方法应用上述粉末显现不同类型指印并分别于自然光和紫外光下观察比较显现效果。结果不同粒径粉末显现指印于自然光和紫外光下显现效果和发光颜色不同。结论针对背景颜色和指印类型选用不同粒径粉末。
Objective To evaluate the effects of particle size of nano zinc oxide for latent fingerprints development. Method Fingerprints developed by four different size nano zinc oxide were compared under UV light and white light. Result Fingerprints developed by different sizes powders were different under two kinds of light. Conclusion In consideration of the type of the fingerprints and the color of backgrounds, we should chose proper size of nano zinc oxide.
