  For the work function of the HOMO energy level of metal and organic semiconductor materials, it has a very important impact on the performance of components, such as organic field effect transistors (OFETs), organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic electronic luminescence. And organic thin film solar cells. Generally speaking, for UPS and XPS, the ionization energy/work function measurement can only be carried out while measuring the photoelectron spectroscopy of the sample under high vacuum conditions. However, organic devices are affected by the atmosphere, which leads to certain requirements for measurement under various atmospheric gases. Using photoelectron spectroscopy, our BIP-KV201 ionization energy measurement system can detect some samples under nitrogen protective gas, vacuum gas and atmosphere. Using nitrogen purging type monochromator and optical system, BIP-KV201 direct vacuum ultraviolet rays on the sample, the work function can reach 9.54eV.

  
  

  
  

  
  

  
  

  
  

  For metal and organic semiconductors, a strict test environment such as ultra-high vacuum is always required to accurately determine the electronic structure. As a result, the cost of testing increases, and the test time also increases. Therefore, a simple and practical test method is very meaningful for scientific research and industrial R&D. The BIP-KV201 ionization energy test system is a unique tool that can characterize the energy level of functional materials in different environments. Compared with the traditional photoelectron emission spectroscopy, due to the free air environment of BIP-KV201, the test time and cost are greatly reduced, and the accuracy of the test is greatly improved.

  Yield photoelectron spectroscopy analysis

  
  

  Monochromatic light is irradiated on the sample. At present, a large number of photoelectrons released from it can be detected, and a large number of photons in the excitation monochromatic light can be detected. Then the ionization energy is detected at the constantly changing inlet.

  ①Background measurement

  
  

  A photomultiplier is used to measure a large number of photons by irradiating the sample with light.

  
  

  ②Sample measurement

  
  

  Monochromatic light of each wavelength irradiates the sample, but the voltage applied to the sample can easily capture the released electrons. And calculate the large amount of electrons currently released.
