Abstract
The first excited triplet state of NaNO2 single crystals and crystals doped with 1% KNO2 has been investigated using optically detected magnetic resonance in zero field. Three different triplet states could be distinguished: Mobile excitons, localized traps (z) due to the dopant KNO2 in the doped crystals and NaNO2-traps. The corresponding zero-field splitting parameters are Dexc = 0.45611 cm−1, Eexc = −0.04779 cm−1, Dz = 0.43570 cm−1 and Ez = −0.04912 cm−1. For the NaNO2-traps only the E-values can be given to have the respective values −0.04829 cm−1, −0.04873 cm−1, −0.04875 cm−1 and −0.05010 cm−1. Optically detected hole-burning experiments proved that the exciton ODMR-line is homogeneously broadened, whereas the trap signals are inhomogeneously broadened by second order hyperfine interaction with the 14N nucleus.
