Two thin film fabrication devices on liquid surface

KSV minitrough system
It is also called “Langmuir-Blodgett (LB) film fabrication system”.
A PTFE Langmuir trough (shallow container) is filled with liquid as a subphase. The molecule is spread onto the subphase, and the thin film is fabricated on liquid surface.
Two barriers which are set up at right and left of the Langmuir tough are moved, and the forming state of thin film is investigated by measuring the surface pressure.
The prepared thin film is deposited onto the substrate by the horizontal dipping method.
The movement of barriers and dipper is controlled by PC.
There are two systems bearing same specifications.


Brewster angle microscope

The formation of thin film on liquid surface is observed by utilizing reflection phenomenon of light. This microscope with the thin film fabrication system makes automatic shooting and video recording possible.

UV-vis-IR absorption spectra measurement device

JASCO V-670 spectrophotometer
The absorption spectra is measured by irradiating UV-vis-IR light (measurement wavelength range: 190‒2700 nm).
The measurement of not only solution but also thin film is possible. The diffuse reflectance spectra of powder and colloid solution can be also measured by employing an integrating sphere.


IR absorption spectra measurement device

JASCO FT-IR 6200 spectrometer
The absorption spectra is measured by irradiating IR light (measurement wavenumber range: 7800‒350 cm-1).
The sample chamber is vacuumed and displaced by inert gas, which eliminates the effect of water and CO2 in the atmosphere. By the transmission method, the measurement of sample powder diluted with KBr (In our lab, there is a KBr plate set which can prepare KBr samples briefly) and thin films.
Moreover, by the ATR method, the special measurement of microscale sample and sample surface is also possible.
As the prism for ATR, germanium and diamond are prepared.
In the transmission and ATR methods, this system is fixed so that the place of sample is kept sealed.
Thus, the active sample can be measured by preparing in the glove box.
In addition, by the RAS (Reflection-, Absorption Spectroscopy) method, the absorption spectra of super-thin film prepared on the substrate including gold can be measured, too.


Fluorescence spectra measurement device

HORIBA SPEC Fluorolog-3
The sample is irradiated by the excited light whose source is 450 W xenon lamp, and the dispersion of the obtained fluorescence affords spectra.
The double grating spectroscope is set up at the both sides of excited light and fluorescence, which removes the stray light.
Thus, spectra can be measured sensitively.
The detecting correspondence wavelength range of the fluorescence side is from 240 to 850 nm. By employing the dedicated cryostat and temperature controller, the measurement at a temperature of liquid nitrogen is possible.


Pseudo sunlight irradiation device (solar simulator)

This device achieves the pseudo sunlight by employing xenon lamp and AM 1.5G filter.

The specific surface area and micropore distribution are investigated by adsorbing gas and vapour into the sample and measuring the amount of adsorption.
The simultaneous measurement of three samples in case of the simple mode and two samples in case of high-precision is possible, respectively.
The heater which can heat up to 450°c is attached, thus the adsorption measurement without taking out the sample is possible by pretreating in the device body. This is why the high-precision measurement of the adsorption amount at low pressure region is possible.
