Abstract
We carried out a laser spectroscopic investigation of high-pressure, high-temperature (HTHP) synthetic diamond
containing NE8 defects. In the photoluminescence (PL) emission spectra the defects have a zero-phonon line
(ZPL) at 794 nm. Under 730 nm excitation the width and position of the ZPL as well as the Debye-Waller factor
showed systematic temperature dependences which were modelled in accordance of a modified model of
impurity defects in solids. A strong dependence of the position of the 794 nm ZPL on temperature suggests that
NE8-containing diamond could be suitable for sensitive optical thermometry above 200 K. Further, the PL in the
NIR spectral range makes the diamond crystalline particles promising temperature sensors for biomedical
applications
