The solubility of two luminophores, 2,5-diphenyl-1,3-oxazole (PPO) and 1,4-bis(5-phenyl-oxazolyl-2) benzene (POPOP), has been determined in water-acetone and water-ethanol solvent systems at 25.0 Β°C. The excited states of PPO and POPOP have been studied in these mixed solvents. The dependence of flu
A series of 4-functionalised-2,5-diphenyloxazoles has been synthesised. Each member of the series has been assessed for the ability to scintillate in the presence of ionising radiation. The scintillation counting efficiency of each member of the series has been determined relative to 2,5diphenyloxaz
