据报道，由于金刚石中中性硼受体结合激子的衰变而产生的发光，其分辨率比以往更高。声子辅助过程的线宽与束缚激子的电子和空穴在有效玻尔半径约0.85 nm范围内的空间局域化一致。在发光的非声子成分中发现了新的精细结构，这是由于局域粒子的基态和激发态的分裂引起的。
Luminescence produced by the decay of excitons bound to neutral boron acceptors in diamond is reported at higher resolution than hitherto. The line-widths of the phonon-assisted processes are consistent with the electron and hole of the bound exciton having a spatial localization within an effective Bohr radius of about 0.85 nm. New fine structure is reported in the no-phonon components of the luminescence, caused by splittings in both the ground and excited states of the localized particles.
