Combustion synthesis and photoluminescence study of silicate biomaterials

摘要

Silicate based bioceramics are promising candidates as biomaterials for tissue engineering. The combustion synthesis method provides control on the morphology and particle size of the synthesized material. This paper discusses the combustion synthesis of akermanite (Ca_2MgSi_2O_7 and Sr_2MgSi_2O_7), which has been shown to have good in vitro and in vivo bioactivities by earlier studies. Both Ca_2MgSi_2O_7 and Sr_2MgSi_2O_7 have akermanite structure. Ca_2MgSi_2O_7 and Sr_2MgSi_2O_7 were prepared using urea and ammonium nitrate. The combustion synthesis using urea and ammonium nitrate was found to be cost effective and efficient method of synthesis. The photoluminescence study of Ca_2MgSi_2O_7: Eu~(2+) and Sr_2MgSi_2O_7: Eu~(2+) shows host specific intense emission of Eu~(2+).
