Measurements of absorption, fluorescence and phosphorescence spectra, quantum yield and lifetime of organic compounds in solutions and thin films.

Fluorescent or phosphorescent compounds have to absorb and emit light at spectral range from 196 nm to 957 nm.
Quantum yield is measured by comparing with etalon materials.
Etalons: quinine suphate, fluorescein, sulforhodamine 101, Nile blue perchlorate, 5-carboxytetrametylrodamine.
One sample per measurement.
Compounds should exhibit strong absorption in the spectral range from 196 nm to 957 nm, solubility in common organic solvents (acetone, THF, toluene, DMSO, DMF, ethanol, methanol and etc.)
Quantum yield measurement accuracy of 5%.
Temperature range from 8 K to 300 K. 

Application. Characterization of optical parameters in 8-300 K temperature range of new organic compounds will enable to evaluate their potential for applications in organic electronic devices (organic light emitting diodes, organic solar cells, sensors).
