摘要
The photoluminescence of Eu3+-doped yttrium oxide chloride embedded in nanoporous glass has been observed. In comparison with those in the powder phosphor, the emission lines of Bu3+ ions become much broader and blueshift was observed in the lines due to (5)Do --> F-7(2) transitions and the Eu-O charge transfer excitation band. The ratio intensities of the (5)Do --> F-7(1) transitions to the D-5(0) --> F-7(2) transitions of Eu3+ ion become higher and change at different excitation wavelengths, such as 393nm and 254 mn. The two excitation wavelengths belong to the 4f --> 4f transition of the Eu3+ ion and the Eu-O charge transfer, respectively. This material may be developed into a new luminescent glass.
