Abstract The photoluminescence of Eu3+-doped yttrium oxide chloride embedded in nanoporous glass was observed. The emission lines of Eu3+ ions become much broader and blue shift were observed in the lines due to 5D0 → 7F2 transitions and Eu-O charge transfer excitation band in comparison with those in the powder phosphor. The ratio intensities of the 5D0 → 7F1 transitions to the 5D0 → 7F2 transitions of Eu3+ ion becomes higher and change at different excitation wavelengths such as 393 nm and 254 nm. The two excitation wavelengths belong to the 4f → 4f transition of Eu3+ ion and the Eu-O charge transfer, respectively. This material may be developed into a new luminescent glass.
