Using red (633 nm) light instead of green (532 nm) light produced nearly 100% spin-dependent readout contrast and a threefold improvement in calculated DC magnetic field sensitivity. However, red light also caused pronounced emission blinking, while green light yielded stable emission. Combining both wavelengths stabilized blinking at a slight cost to contrast, revealing a fundamental trade-off between emission stability and signal strength. The findings suggest wavelength-level optimization per individual defect could advance 2D quantum sensors and enable super-resolution imaging. ## Full article daily.dev links to this article rather than hosting it.
