With advancement of technology, requirements for light-emitting devices are increasing. Various types of packaging technologies have been suggested to improve the performance of light-emitting diode (LED). Among them, phosphor in glass (PiG) is attracting attention due to its manufactural facility and easily tunable characteristics. As PiG draws increasing attention, research on glass materials is also being actively conducted. However, studies about glass in the field of phosphor are mainly conducted on fabrication. Only a few studies about recycling have been reported. Thus, the objective of this study was to recycle waste glass discarded in other fields due to breakage and failure and use it to fabricate phosphor in glass. Cylindrical waste glass was pulverized into powder with an average size of 12 μm, mixed with a phosphor and sintered to be reborn as a phosphor in glass to broaden the recycling route for waste glass.
随着技术的进步,对发光器件的要求也在不断提高。为了提高发光二极管 (LED) 的性能,已经提出了各种类型的封装技术。其中,玻璃中的荧光粉 (PiG) 因其制造工艺简单和易于调谐的特点而受到关注。随着 PiG 越来越受到关注,对玻璃材料的研究也在积极进行。然而,在荧光粉领域的玻璃研究主要集中在制备上。只有少数关于回收的研究报告。因此,本研究的目的是回收因破损和失效而丢弃在其他领域的废玻璃,并将其用于制备玻璃中的荧光粉。将圆柱形废玻璃粉碎成平均粒径为 12 μm 的粉末,与荧光粉混合,烧结,重新制成玻璃中的荧光粉,拓宽废玻璃的回收途径。
