With the decrease of the coplanarity of thiophene derivatives or its feed ratio, the PL and EL spectra can be blue shifted.

The resulting materials were characterized by x-ray diffraction, Fourier transform infrared spectroscopy, Nuclear magnetic resonance and Photoluminescence. Those spectra reveal that by adding SiO2 to YAG:Ce precursor, the lattice constant decreases while vacancies are generate due to the co-dopant ions (Si4+) replaces in the place of Al3+ sites of YAG:Ce system. YAG:Ce phosphors with Y3+ dodecahedral site replaced by Ce3+ and diffused effectively as an activator, as a result the photoluminescence intensity increased about ~20-30%.

研究成果显示,掺杂SiO2之YAG:Ce萤光粉经过高温热处理后,由X光绕射、红外线吸收光谱仪以及核磁共振可以得知,当SiO2添加量增加时,YAG:Ce晶格常数会因为Si4+取代Al3+的四面体晶格位置而变小,同时产生将YAG:Ce之铝离子空位缺陷,使活化中心更有效地在YAG:Ce主体中扩散取代Y3+的十二面体晶格位置,提高其发光性质约20~35%。
