研究目的
Investigating the vertical detachment energy and adiabatic electron affinity of Alq3 to estimate the reorganization energy for electron transport in bulk Alq3.
研究成果
The study successfully determined the VDE and AEA of Alq3 and estimated the reorganization energy for electron transport in bulk Alq3. The findings contribute to the understanding of electron transport properties in organic semiconductors.
研究不足
The AEA value could not be determined unambiguously because the (0, 0) origin peak is not visible in the spectrum. The experimental λ bulk value is larger than the calculated value, indicating potential discrepancies between experimental and theoretical approaches.
1：Experimental Design and Method Selection:
The study involved generating a molecular anion of Alq3 using a pulsed discharge nozzle (PDN) under supersonic expansion and recording its photoelectron spectrum after mass selection.
2：Sample Selection and Data Sources:
The solid sample of Alq3 was used to generate the molecular anion.
3：List of Experimental Equipment and Materials:
A PDN modified for solid samples, a time-of-flight mass spectrometer (TOF-MS), and a magnetic bottle-type photoelectron spectrometer (MBPS) were used.
4：Experimental Procedures and Operational Workflow:
The anion of Alq3 was generated, mass-separated, and then irradiated by an unfocused second harmonics output from an Nd:YAG laser. The photoelectrons were detected and their spectra were obtained by accumulation and smoothing.
5：Data Analysis Methods:
The binding energies of the photoelectrons were calibrated, and the photoelectron spectra were analyzed to determine the vertical detachment energy and adiabatic electron affinity.
