Formatted abstract
An unusual two- to threefold decrease in the luminescence intensity of nitrogen-vacancy centers in 30 nm diamonds under increasing pulsed-laser irradiation (up to the level of 0.1 J cm−2) has been measured. The effect showed little dependence on the pulse repetition rate below 1MHz and was accompanied by insignificant changes in the emission spectrum. The primary cause of the effect was attributed to the heat generated by the laser pulse and the consequent increase of the crystal temperature, which was estimated in the range of 300–400 °C.
