研究目的
Investigating the effects of low-power He-Ne laser irradiation on high-pressure high-temperature nanodiamond films, focusing on the transformation of sp3-carbon to sp2-carbon and the accompanying light emission in the green region of the optical spectrum.
研究成果
The study demonstrates the possibility of modifying HPHT nanodiamond films using low-power He-Ne laser radiation, leading to the transformation of diamond material into sp2-carbon accompanied by light emission in the blue-green region. This phenomenon is attributed to the ionization of impurity complexes of Ni and Ni-N within the nanodiamonds.
研究不足
The study is limited to the effects of 632.8 nm laser irradiation on HPHT nanodiamond films. The mechanisms behind the observed phenomena require further investigation to fully understand the role of impurity complexes in the transformation process.
