Realization of a green-emitting pyrosilicate-structured Er3+-activated Y2Si2O7 phosphor: a systematic study of opto-electronic characteristics and thermal stability for lighting applications

A series of green-emitting Y 2− x Si 2 O 7 : x Er 3+ phosphors ( x = 1–7 mol%) have been successfully synthesized using a straightforward gel-combustion method facilitated by urea.
