Bond distances binary solids

The pursuit for new phosphors has recently focused on compounds that form complex solid solutions, which provide a mechanism to tune the luminescent properties. The emission color of the binary system— Mi xM x)2Si04 Eu (M/M = Mg, Ca Sr, Ba)—can be mned from violet to red-orange, and the thermal stability is dependent on the components and ratio of M/M. The bond distance of M/M = O and the volume of the unit cell greatly affects the optical properties of this system. A longer M/M = O bond distance and large unit cell provide a weaker crystal field, which results in a blue-shift emission. Moreover, a distortion of the crystal structure can also provide tunable optical properties of the phosphor [3]. [Pg.400]
