In recent years, the formate ion (HCO2−) as a kind of hole-to-electron converter has attracted much attention of photographic researchers. The formate ions can trap photo-generated holes, eliminate or reduce the electron loss caused by electron–h

We investigate the decay process of photoelectrons from a luminescent material of ZnO:Zn using a microwave dielectric spectrometry. Electrons in the conduction band are found to decay exponentially and the lifetime is 781 ns, while the time interval

The influence of K4Fe(CN)6 at various doping concentrations on the photosensitivity of cubic AgCl microcrystals has been investigated by using the microwave absorption and phase-sensitive measurement technique. The time behaviour of free photoelectro

A model is proposed to describe the photoelectron decay process at room temperature in cubic AgCl microcrystals homogeneously doped with K4Fe(CN)6. By combining calculation of the kinetic equations resulted from the model with a microwave absorption

A YAG supershort pulse laser (355nm, 35ps) is used as an exposure source and the microwave dielectric spectrum technique is used to quickly detect the photoelectron decay process in AgX microcrystals, because the free photoelectron lifetime and decay

The photoelectron decay characteristic of AgCl micro-crystal, which adsorbed with the green-sensitive cyanine dye, has been obtained by using the microwave absorption and phase-sensitive measurement technique. It is found that when the sensitive conc

Electromagnetically induced transparency (EIT) resonance is obtained in a Λ three-level configuration when the coupling field and the probe field satisfy the two-photon resonance condition. When an additional microwave field drives the transition be
