我們研究之鎂矽酸鹽玻璃中所添加之氧化物TiO2及K2O，一般文獻研究可增加產生晶體之數量、 並產生相分離影響玻璃的結晶相及其光學性質，因此希望藉由改變其於組成中之含量產生正確晶相使螢光強度提升，並增加結晶數量及縮小結晶顆粒大小使散射損失降低，研究Ti及K對摻鉻玻璃與玻璃陶瓷之光學及材料特性之影響，進而對組成上進行改良，使能激發1.1~1.6微米螢光波長之Cr4+離子於晶體內部含量增加，並達到奈米等級之結晶減少因晶體過大產生之不必要的散射損失。
對於實驗則分別改變TiO2與K2O在摻鉻玻璃組成中的含量，對其進行光學及材料特性的量測分析。推論出各自之特性後，進而調配其混合之比例，最終調製出最接近本實驗目標特性之樣品，並且將其組成配方進行光纖抽絲製程，期望應用及製作出具有寬頻螢光特性的摻鉻玻璃陶瓷光纖。實驗結果證實，TiO2一般做為成核劑之化合物，對於結晶晶相並無影響，其主要功能在於幫助晶體的形成，從XRD的結果中即可得知。其中最主要影響晶相的為K2O，其添加與否才是影響Mg2SiO4晶相形成的最主要原因。而委託抽製之光纖，其特性也與摻鉻玻璃陶瓷相同，證明於玻璃陶瓷之研究可運用在MCVD並抽製成光纖，是為後續研究可運用及改進之方向。

We studied the magnesium silicate glass Oxides TiO2, and the added K2O, general literature to increase the quantity produced crystal and glass phase separation effects and optical properties of the crystalline phase, so I hope by changing its composition the content of the crystalline phase to produce the correct fluorescence intensity increase, and increase the number of crystallization and reduce the scattering loss crystalline particle size reduction, research on chromium doped Ti and K glass and glass-ceramic material properties of the optical and the impact on the composition and thus make improvements to enable fluorescence excitation wavelength of 1.1 to 1.6 microns of Cr4 + ions in the crystal internal content increases and reaches the crystallization of nanometer-scale crystals reduce excessive scattering loss incurred unnecessary.
For the experiments were changes in chromium-doped TiO2 and K2O content of the glass composition, and its optical measurement of material properties. And to infer the characteristics of each post, and then deploy the mixing proportion, culminating in the modulation of the closest to the target characteristics of the samples in this experiment, and its composition formulations fiber spinning process, application and production expectations having broadband fluorescence characteristics chromium-doped glass ceramic fibers. Experimental results show that, TiO2 generally the compound as a nucleating agent for crystallization crystalline phase had no effect, and its main function is to help the formation of crystals from the XRD results. The main impact of the crystalline phase of K2O, add it or not is the impact of Mg2SiO4 crystal phase formed the most important reason. Commissioned by the optical pumping system, and its characteristics are the same as with chromium-doped glass ceramics, glass ceramics research evidences can be used in MCVD and pumped into fiber for future research may use and improvement of orientation.
