luminescence

It is a fast and sensitive reader that combines the use of optical filters and two monochromators. It comes with application-specific optical mirror modules, a xenon flash lamp and two high-speed detectors. EnVision also has a standard module for measurements in AlphaScreen ™ technology (PerkinElmer), temperature control, code reader, dispenser and 13 optical filters. The instrument has a 1- to 384-well plate format, scans the cell test well area, and has the ability to read fluorescence from the bottom of the plate.

The laboratory is equipped with a set of portable chambers with diamond anvils enabling the application of high pressure (up to 30GPa) to the tested materials. The laboratory enables the following measurements as a function of pressure: excitation spectra of luminescence, Raman spectra, photoluminescence spectra and luminescence kinetics. The ability to measure excitation spectra or luminescence kinetics both as a function of pressure and temperature (10 - 600 K) makes it a unique laboratory on the global scale.

The gas pedal consists of three modules: ion source, gas pedal and measurement chamber. In the measurement chamber there is a system to form a perpendicular beam of atoms or thermal molecules. Additionally in the ion beam path an exchange chamber is implemented, to neutralize the ion beam. Photons emitted by excited atoms or ions are recorded by photon counting method. The design of the collision chamber enables registration of light coming directly from the collision point or at some distance from it. The laboratory enables analyses of small ion collisions at energies up to 25 keV.

The apparatus consists of 3 large vacuum chambers. In the first of them there is an ion source, in the second - a mass spectrometer with electron optics, forming the ion beam, in the third - a collision cell with an observation window. The light generated in collisions inside the collision cell is projected outside by a system of mirrors to the spectrograph. By using a multi-channel detection system with single photon counting, the measurement system is very sensitive. The laboratory enables spectroscopic study of atomic and particle collisions, and chemiluminescence studies.

The laboratory enables registration of stationary absorption, fluorescence excitation, fluorescence and phosphorescence spectra in the temperature range 77 - 340 K and phosphorescence decay curves. It is equipped with a Langmuir-Blodgett bath for obtaining and studying monomolecular layers at liquid-gas or liquid-liquid interfaces and transferring such layers onto solid substrates. The infrastructure can be used for spectroscopic analysis of monomolecular layers and their deposition on solid substrates.
