摘　　要：提出了巯基丁二酸包覆的CdTe量子点溶液显现潜指纹的新方法,在溶液pH值等于10.5、显现温度为25℃的条件下得到了优异的显现效果。显现时间仅需1～3s,比文献报道的同类方法快,并可应用喷显法显现指纹,从而可以拓展客体的显现范围。A new method of developing latent fingerprints by MSDS/CdTe QDS was explored. Excellent results were obtained in the conditions of pH= 10. 5 and 25℃ developing temperature. One to three seconds of developing time is much shorter than the similar method which was reported in the literature. Moreover, successful application of spraying development expands its range of development.
