All PID curves obtained were fitted by three analytical expressions derived from OTOR delocalized and localized models as well as from a tunneling (localized) recombination model. The results showed that the PID effect presents a weak dependence of decay temperature yielding activation energy values much lower that the values of initial rise. Special attention was given to fitting parameters which are microscopic quantities characteristic of the trapping and recombination systems.

At harvest, plant width, height, leaf number, and individual fresh weight were notably increased, with fresh weight rising by approximately 21.5%.

Comprehensive experimental and density functional theory (DFT) analyses reveal that Li+ substitution facilitates carrier delocalization. Temperature-dependent photoluminescence identified a shallow 17 meV de-trapping barrier from the self-trapped exciton (STE) to the free exciton (FE) state.

The emergence of the FE component enables a rapid scintillation decay time of less than 100 ns. In addition, Li2HfI6 achieves a high thermal neutron light yield of 17,000 photons/neutron, which is approximately three times higher than commercial 6Li-glass.
