| Abstract |
| Nickel oxide doped lithium strontium borate glasses were prepared by conventional
melt-quench method. X-ray diffraction studies confirmed the amorphous nature of
the sample. Density increases whereas molar volume decreases with the addition of
nickel oxide. Glass bond density, boron-boron separation and oxygen packing density
were estimated using standard formulae. Polaron radius, inter ionic distances and
field strength exhibit composition dependent trends. Fourier transform infrared
spectroscopic studies revealed the presence of short-range structural units such as
diborate (B4O7
2–), dipentaborate (B5O17
2–), pyroborate (B2O5
4–) and metaborate units
(BO2O–) in the borate glasses. Photoluminescence studies revealed four emission
bands centered at 486, 521, 547 and 623 nm. An intense emission peak was observed
at 487 nm. Commission internationale de l’éclairageand correlated colour temperature
studies suggested that the investigated glasses emit blue light at 1741-1809 K.
