隨著綠色能源材料逐漸受重視，白光發光二極體在日常生活中的應用越來越普遍，故開發可搭配商用晶片之高發光效率與高演色性的螢光材料是目前發展白光發光二極體的重要議題之一。本研究將分為三個部分：第一部分利用固態反應法來製備CaTiO3摻雜Eu3+之紅色螢光粉，並共摻雜Li+以探討摻雜對發光行為與色純度提升之影響。根據研究結果發現Li+的添加可以增加Eu3+在CaTiO3中的有效固溶度和減少鈣空缺，以提升多重聲子過程的遷移速率以改善發光性質及造成衰減時間變短，使發光強度明顯提升1.6倍。此外，隨著Eu3+和Li+的增加，Ca1-2xEuxLixTiO3紅色螢光粉之色度座標會比商用Y2O2S:Eu紅色螢光粉更接近理想紅光(0.68, 0.32)，最佳摻雜樣品可提高色純度至92.1%。這些結果顯示擁有高色純度的Ca1-2xEuxLixTiO3 紅色螢光粉具有可信賴的應用性，可作為商用紫外光晶片與藍光晶片搭配的固態光源之白光混光應用材料。
第二部分為以固態反應法製備可與商用450nm藍光晶片搭配之Ca3Sc2Si3O12:Ce3+綠色螢光粉以混成白光，並共摻雜不同濃度Al3+以期提升Ca3Sc2Si3O12:Ce3+綠色螢光粉之發光表現。由本研究結果可知，摻雜Al3+能有效抑制雜相Sc2O3與CeO2的形成，提升樣品之純度、結晶性與發光強度，同時增加Ce3+能階的晶格場分裂，導致光致發光光譜往紅光波長位移。並利用高強度同步輻射光源之XANES分析可探討元素之電子價態結構，證明摻雜之Al3+能取代在主體中Sc3+的位置，並可清楚觀察到Ce3+與Ce4+的變化量以及Ca原子周圍環境對稱性的改變。
第三部分為以熱碳還原法取代固態反應法製備摻雜Al3+之Ca3Sc2Si3O12:Ce3+綠色螢光粉。由結果顯示，此方法可以有效的減少雜相的殘留，且提高Ａl3+在Ca3Sc2Si3O12:Ce3+綠色螢光粉體中的最佳摻雜濃度(x)，相較於固態反應法，Al3+的最佳摻雜量可由x=0.05增加至x=0.15， 其量子效率則可從46.8% 提高至51.6%，且熱碳還原法能有效提升Ca3Sc2Si3O12:Ce3+之發光強度及量子效率，最佳摻雜之量子效率更可由46.8%提升至51.6%，顯示熱碳還原法相較於固態反應法更能提升Ca3Sc2Si3O12:Ce3+綠色螢光粉的發光表現，使其更具有實際應用之潛力。

High color purity red phosphors of Ca1-3/2xEuxTiO3 and Ca1-2xEuxLixTiO3 (0 < x ≤ 0.3) are synthesized via a solid-state reaction method. The red emission photoluminescence intensity and color purity are enhanced by the incorporation of Li+ into CaTiO3:Eu3+. Li+ doping increases the emission probability from 5D0 state，increase photoluminescence intensity by 1.6 times，increases color purity to 92.1%，and shortens the decay time. With increasing Eu3+ and Li+ content，the color coordinates approach the ideal red chromaticity values，coming closer than commercial Y2O2S:Eu3+ red phosphor.
Ca3Sc2Si3O12:Ce3+ (CSS:Ce) green phosphors used for white light-emitting diodes (LEDs) are synthesized and co-doped with Al3+ via a solid-state reaction method. The incorporation of Al3+ into CSS:Ce can inhibit the formation of the impurity phases Sc2O3 and CeO2，improve crystallinity，and enhance the photoluminescence intensity as well as quantum efficiency. The substitution of Sc3+ with Al3+ increased the crystal field splitting of Ce3+ and resulted in the red shift of photoluminescence. The results show that Ca3Sc2-xAlxSi3O12:Ce3+ has high quantum efficiency，making it a promising green phosphor that can be collocated with a commercial 450 nm blue LED and a red phosphor for solid-state lighting applications.
Al3+ co-doped Ca2.955Sc2Si3O12:Ce3+ (CSAS:Ce) green phosphors were also systematically investigated using X-ray absorption near-edge spectroscopy (XANES) to understand the influence of Al3+ incorporation on photoluminescence behavior. XANES results indicate that Al3+ occupies the Sc3+ sites and stabilizes the crystal structure of the host material. Furthermore，Al3+ can effectively inhibit the oxidization of Ce3+ to Ce4+，which enhances the photoluminescence of CSAS:Ce green phosphors.
CSAS:Ce green phosphors are also synthesized by carbothermal reduction method. The structure analysis shows the doping suitable Al3+ content can inhibit residual impurity phases. Furthermore, Al3+-doping also can improve the optical properties. The optimal Al3+-doping content can upgrade from x=0.05 to x=0.15. The quantum efficiency can be enhanced from 46.8% to 51.6%. These results present that the carbothermal reduction method is better way to increase the optical performance of CSAS:Ce green phosphors, than the traditional solid-state reaction method.
