Fu-Hai Yang Photoluminescence investigation of green-emitting magnesium stannate phosphors
Mu-Tsun Tsai;Fu-Hai Yang

We experimentally investigate the photoluminescence properties of un-doped and Mn-doped Mg2SnO4 (MTO) powder phosphors via a sol–gel process. The intrinsic luminescence of MTO exhibits green-light emission under UV excitation. Significant enhancement in emission intensity was demonstrated for the MTO:Mn phosphors.

Xung Jing Peng The Characteristics of Double Ring Remote Phosphor Geometry for Phosphor-Converted Light-Emitting Diodes
Xung Jing Peng;Ping Shang Ying

The characteristics of double ring remote geometry for phosphor-converted light-emitting diodes are proposed in this study. The optical characteristics of the mixed and double ring remote pcLEDs with different phosphor concentration are discussed.

Yu-Chun Liu Development of Adaptive One-dimensional Drift-diffusion Charge Control Solver TCAD Tool for Optoelectronic Device Modeling
Yu-Chun Liu;Chien-Hsien Lin;Bor-Hann Huang;Yuh-Renn Wu

The Python based User friendly DDCC-CAD tool for solving drift-diffusion charge-control solver developed by NTU and ITRI is presented here. An adaptive algorithm approach will be applied and tested. The goal is to assist users automatically fitting the experimental results and find the optimized solutions of optoelectronic devices.

Ya-Xun Lin Self-assembly of microlens arrays using spin-coating process and their optical properties
Ya-Xun Lin;Shao-Ju Lin;Su-Hua Chen;Mao-Kuo Wei

10-um surface-modified silica microspheres, organic solvent and polymethylmethacrylate were used to fabricate self-assembled microlens arrays on glass substrates. The microlens arrays can improve luminous efficacy of organic light-emitting devices more than 40%. Their optical properties including CIE indices and spectra were also investigated.
