摘要：
The photoluminescence (PL) behaviour of PVA-PTAA blends of different composition is investigated. It is observed that the interchain interaction have an important effect in this system leading to an unexpected decrease in the PL intensity as the PTAA content increase. An enhancement of the PL intensity as function of the time was also detected for all samples which were irradiated by laser. Using laser intensitiy of 18 W/cm(2) it was observed an increase of 93% in PVA-PTAA 1 wt% blend. Using this methodology it was possible to build an emission pattern.
