摘要：

The present work reports the excitation dependent photoemission properties of Er3+/Sm3+ co-activated multi component borosilicate glasses prepared through melting and rapid quenching technique. The energy transfer (ET) from Er3+-> Sm3+ ions within the co-doped glasses was confirmed by means of spectral overlap diagram, photoluminescent emission spectra and the decay time profiles. The appreciable variation in emission intensity and the average lifetime values along with the rise in Sm3+ ion concentration substantiates the presence of ET and the estimated CIE co-ordinates corroborates that the prepared glasses emanate light in both cool white and reddish-orange region with respect to the applied excitation wavelengths.
