Abstract


As the first step to design nanosystems for X-ray excited sensitising of singlet oxygen, nanoparticles of polystyrene (PS NP) and polystyrene with encapsulated diphenyloxazole molecules (PS-PPO NP) were synthesized. Inside the PS-PPO NP, the electronic excitation energy transfer from polystyrene matrix to encapsulated PPO molecules takes place; efficiency of such transfer was roughly estimated to be about 0.37. X-ray stimulated luminescence of PS-PPO NP was registered.

Keywords
