摘要：

Photobleaching of three different xanthene dyes namely, Erythrosin B (ERB), Eosin Y (EOY) and Rose Bengal (ROB) in Poly(Vinyl Alcohol) (PVA) matrix has been studied. Quantum yield values of photobleaching using an argon-ion laser (514.5 nm) were determined in presence of an electron donor (TriEthAnolamine, TEA) and/or Cr(VI). Evaluated quantum yield values suggest that erythrosin B undergoes faster photobleaching than eosin Y or rose bengal in presence of TEA. Presence of Cr(VI) in addition to TEA drastically decreases the quantum yield. Possible reaction pathways of photobleaching are discussed.
