無機鈣鈦礦量子點發光二極體之光學特性與可靠度研究

Study on Optical Property and Reliability of Inorganic Perovskite Quantum Dots LED

指導教授 : 林建中 郭政煌

摘要


本論文中使用無機鈣鈦礦量子點與發光二極體嘗試改變激發波長、封裝差異、濃度比例與添加散射材料ZrO2,目的是了解鈣鈦礦量子點結合發光二極體的最佳化。 無機鈣鈦礦量子點利用水解法包覆在二氧化矽中,隔絕外界水氣與氧氣接觸造成量子點自聚集或劣化,將已包覆的鈣鈦礦量子點/二氧化矽複合材料混合二甲基矽氧烷封裝至LED上,通電流於LED使短波長光激發位於上方的量子點,長時間激發量子點量測分析光譜之變化,由多次條件測試元件可靠度。

In this thesis, all inorganic halide perovskite quantum dots and light-emitter diodes are used to verify excitation wavelength, encapsulate difference, concentration ratio and the addition of high scattering material Zirconium dioxide in order to optimize the inorganic perovskite quantum dots hybrid light-emitter diode. The quantum dots were coated in silicon dioxide by hydrolysis method to separate the contact between external moisture and oxygen to cause self-aggregation or degradation of quantum dots. We use perovskite quantum dots coated in silica encapsulated on light-emitter diode with polydimethylsiloxane(PDMS). Pumping the quantum dots with higher energy photon from LED chips. Continuously long-term lighting the PQD analysis the change of spectrum and the reliability of the devices is tested by multiple conditions.
