However, porous silicon exhibits photoluminescence (PL) property in visible range. It opens a new window to develop photoelectric industry. The light emitting properties of porous silicon are studied. Various porous silicon wafers are used to obtain the micro-sized silicon particles which have a lot of nano-scaled pores and pillars. The particles are combined with reains to from an available light emitting ingot. The Scanning Elector Microscope (SEM)、Photoluminescence (PL)、Integrating sphere and Particle size distribution (PSD) are used to measure the photoelectric properties. The oxidation on the surface of porous silicon is the main issue which decays the intensity and lifetime of light emitting. It also leads to a blue shift on the light emitting wavelength. The new methods proposed in the study can extend the lifetime of light emitting ingot. Besides, the Brunauer-Emmett-Teller (BET) are used to measure the surface area to volume ratios. A high ratio can be obtained on the smaller silicon particles. In addition, the transmittance and reflectance of the light-emitting ingots are measured by Integrating sphere. In the study, the light emitting ingots with small silicon particles can emitte a stable visible lights in room temperature for a much longer time compared with conventional porous silicon thin films. PS almost applied to the sensor、phtotdectector、solar cells …. We wish for more application to the porous silicon particle. Jia-Chuan Lin Chuen-Huei Tsau 林嘉洤 曹春暉 2010 學位論文 ; thesis 80 zh-TW |
