To improve luminescent intensity of Sm3+, series of host materials were prepared and studied .Shi Pengtu[2] studied the luminescence properties of CaO-SiO2-B2O3 glass doped with Sm3+ .
Ye Renguan[4] prepared a Eu2+/Sm3+ co-doped silicate glass and the result of the experiment indicate it to be a potential materials for white light-emitting diodes (WLED).Sun Ting [5] proved an organic material HTTA a good ligand of Sm3+ for red fluorescence.
Very strong luminescence at around 599nm is observed in glass-ceramics , This indicates glass-ceramics a better host for Sm3+ than precursor glass and a hopeful laser material.
