Luminescence properties of epoxy resins modified with a carbazole derivative

Luminescence properties of a new material ‐ epoxy resin with added 9‐(2,3‐epoxypropyl)carbazole (REPK) were studied. Absorption and photoluminescence (PL) spectra of REPK are compared with those of poly(N‐vinylcarbazole) (PVK). PL in REPK is shifted to shorter wavelengths. Its intensity is higher th...

Summary:Luminescence properties of a new material ‐ epoxy resin with added 9‐(2,3‐epoxypropyl)carbazole (REPK) were studied. Absorption and photoluminescence (PL) spectra of REPK are compared with those of poly(N‐vinylcarbazole) (PVK). PL in REPK is shifted to shorter wavelengths. Its intensity is higher than in PVK. REPK emits light in the range from 330 nm to 470 nm. PL spectrum of REPK could be well deconvoluted for four emission bands.
