Photomodification of CdSe nanocrystals incorporated in a poly(butylmethacrylate) polymer film

A study of the influence of high intensity laser light on the optical properties and exciton relaxation dynamics in CdSe nanocrystals passivated by tri-n-octylphosphine oxide and dispersed in the optically clear poly(butamethacrylate) polymer is reported. The modification of the optical properties of the CdSe/PBMA film is observed after exposure to high intensity laser pulses.
