Low Energy Inverse Photoemission Spectroscopy (LEIPS)

managed by JST

TECHNOLOGY DESCRIPTION

- Electron affinity (LUMO Level) is the key parameters for the R&D of the organic electronics.
- Conventional Inverse Photo-emission Spectroscopy (IPES) has a concern that target materials are easy to be damaged and Energy resolution is low.
- Low-Energy Inverse Photoemission Spectroscopy (LEIPS) could solve this issue.
International publication number: WO 2015182641

BENEFITS

- Almost no damage onto the target materials
Use of low-energy electron reduces damage to the target material.
- Easy adaption of the standard spectroscopy technology
Emitted photon energy(hν) shifts from VUV to NUV region.
VUV : Vacuum Ultra Violet
NUV : Near Ultra Violet
- Resolution improvement
Detection precision/resolution is improved a factor of 2 (< 0.3 eV)
- available at low vacuum condition

LIMITATIONS

N/A

APPLICATIONS

R&D of organic electronics such as organic light emitting diode and organic photovoltaic cells.

MATERIALS

Readiness Level (TRL)

9
actual system proven in operational environment(The pie chart refers to the entire portfolio contained in the database of the helpdesk)

Technology Readiness Levels (TRL) are a method of estimating technology maturity of Critical Technology Elements (CTE) of a program during the acquisition process. The use of TRLs enables consistent, uniform, discussions of technical maturity across different types of technology.
