摘要: Abstract Barium borophosphate glasses doped with dysprosium oxide had been fabricated by conventional melt quenching technique using the chemical composition of: (25BaO: 5B 2 O 3 : 70-xP 5 xDy )), where (x = 0.2, 0.4, 0.6, 0.8 and 1.0, mol%) (BaBPDy). The physical, optical luminescence properties are studied for possibility of as a white materials solid-state light emitting devices. Judd-Ofelt (JO) theory is applied to study radiative level Dy 3+ ions. effect concentration due increase in ions discussed details. lifetime all BaBPDy glass bi-exponential nature, which present work. This non-exponential nature decay curve was fitted well-known Inokuti-Hirayama (IH) model S= 6, indicating that energy transfer process dipole-dipole type. chromaticity co-ordinate(x, y) evaluated from spectra its application has analyzed.
