“…The analysis of the Raman spectra is based on the comparison with homologous compounds [21][22][23] and at the same time with the calculated frequencies of the chain Figure 4 we can be simply observed that NaGd(PO 3 ) 4 Raman spectra is dominated by two well and intense bands at 696 cm -1 and 1184 cm -1 , they are assigned respectively, to the symmetric stretching vibration modes of (P-O-P) and (O-P-O) -. Those bands are characteristic of long chain polyphosphates, so we can therefore confirm that NaGd(PO 3 ) 4 crystallize in chain structure.…”

In this study, investigation on photoluminescence and optical properties of europium doped zinc silicate (Zn2SiO4:Eu3+) glass ceramics derived from white rice husk ash as potential silica source have been done. Undoped and 3 wt. % of europium doped zinc silicate were prepared by solid state method and sintered at 600-1000 °C for 2 h. XRD analysis revealed the phase formation of amorphous, α or β-Zn2SiO4:Eu3+ phases of the glass and glass ceramic samples. FESEM results show the samples were irregular in shapes but well connected and formed large grain crystallites as sintering temperatures increases. The optical band gap values for undoped samples are increasing from 2.97 eV to 3.39 eV respectively. Meanwhile, the optical band gap values for 3 wt. % Eu3+ doped samples decrease from 4.14 eV to 2.62 eV and increase again to 3.71 eV as sintering temperature increases. PL analysis concludes that the red emission exhibited corresponding to 5D0 → 7F2 electron configuration at 612 nm while excitation spectra was found at 400 nm attributed to 7F0 → 5L6 transition. As conclusion, Eu3+ doped Zn2SiO4 glasses has potential as glass host phosphor which can be used for optical devices such as plasma display panels (PDPs) and cathode ray tubes.
