The present invention provides a nanodiamond based physical unclonable functional material, preparation method and applications thereof, comprising a single-crystal silicon substrate and nanodiamond with silicon vacancy color centers grown in situ thereon. The preparation method of nanodiamond particles on the silicon substrate is a stochastic process, which is an essential feature for manufacturing physical unclonable functional labels. The present invention uses scattering spectrum of nanodiamond, the morphological characteristics, and spatial position relationships as fingerprint information for the physical unclonable functional material. Due to the extreme heat resistance, mechanical, chemical and light stability of diamond material. The highly robust label of the present invention can satisfy the requirements of many practical applications in various environments. The present invention has huge applications. The present invention has real commercial value in the anti-counterfeiting market for electronic components, medical packaging, vehicles, luxury goods, etc.
