ABSTRACT

Study of a series of lead lithium borophosphate glass samples was performed to determine the structural and luminescence properties. The glass samples containing the composition of 20PbO-xLi2O-30B2O3-(50-x)P2O5-2TiO2 (where x = 0, 5, 10, 15, 20) system were prepared using melt-quenching technique. The PbO-Li2O-B2O3-P2O5-TiO2 samples were investigated for structural properties using Fourier transform infrared and photoluminescence spectroscopy for studies of luminescence properties. The results from FT-IR showed the presence of trigonal and tetrahedral PO4, PO3, BO4 and BO3 groups within the host network structure. The samples exhibit luminescence emission centered at 420, 482 and 496 nm when excited at 300 nm wavelength. The emission peak at 420 nm were assigned to F center emission and charge-transfer transition of Ti4+ ions. The results showed that emission intensity was dependent on lithium contents in Ti-doped lead lithium borophosphate glass composition.

ABSTRAK

Kajian ini dilakukan ke atas siri sampel kaca plumbum litium borofosfat untuk menentukan struktur dan sifat luminesen. Sampel kaca dengan komposisi 20PbO-xLi2O-30B2O3-(50-x)P2O5-2TiO2 (x = 0, 5, 10, 15, 20) telah dihasilkan melalui kaedah sepuh lindap leburan. Sampel kaca telah dikaji dengan menggunakan spektroskopi inframerah transformasi Fourier dan spektroskopi fotoluminesen. Keputusan kajian daripada FT-IR menunjukkan kehadiran kumpulan trigonal dan tetrahedron PO4, PO3, BO4 dan BO3 dalam struktur rangkaian sistem kaca tersebut. Sampel kaca memancarkan luminesen pada 420, 482 dan 496 nm apabila diuja dengan sinaran 300 nm. Puncak pancaran pada 420 nm telah ditakrif sebagai pancaran pusat F dan proses pemindahan caj bagi ion-ion Ti4+. Keputusan kajian menunjukkan bahawa keamatan pancaran bergantung kepada komposisi litium dalam kaca plumbum litium borofosfat dop Ti.
