Water permeability analysis by D-SIMS
P01960_Water_permeability_analysis_by_D-SIMS.pdf

Use of isotope-labeled water, D₂O, and D-SIMS enables us to clarify permeated D₂O profile after exposure in D₂O vapor. This method is promising for evaluating the water permeation behavior both in inorganic films and organic films.

Determination of multilayer structure of OLED by cross-sectional_TEM
P01963_Determination_of_multilayer_structure_of_OLED_by_cross-sectional_TEM.pdf

Organic layers with similar composition can be distinguished by TEM with our original contrast enhancement. By cross-sectional TEM-EDX of the defect which was found in surface SEM, we can reveal the detailed structure and the composition of it.

TOF-SIMS MS／MS for analysis of degradation product in OLED driving test
P01964_TOF-SIMS_MS_MS_for_analysis_of_degradation_product_in_OLED_driving_test.pdf

PL line analysis, GCIB-TOF-SIMS, and TOF-SIMS MS/MS were applied to the degradation analysis of OLED in driving test. TOF-SIMS MS/MS revealed the detailed chemical structure of degradation product in the specific depth region in OLED stacks.
