位于美国亚利桑那州凤凰城的玫瑰街实验室是一家产品和服务供应商,为私人所有,服务于可再生能源和半导体市场。它宣称第一个证实了基于硅片可以生产长波LED设备,其相比于传统蓝宝石或碳化硅衬底具有很大的成本优势。与紫外线和蓝光LED相比,由于量子效率的下降,制造绿光LED以及长波 Rose Street Laboratories, located in Phoenix, Arizona, USA, is a privately owned and serviced product and service provider serving the renewable energy and semiconductor markets. It claims to be the first to confirm that silicon-based wafers can produce long wave LED devices that offer significant cost advantages over traditional sapphire or silicon carbide substrates. Compared with UV and blue LED, due to the decline of quantum efficiency, the manufacture of green LED and long wave
