In recent years,Perovskite Light-Emitting Diodes(PeLEDs)have received considerable attention in ***,with the development of PeLEDs,commercial applications of full-color PeLED technology are largely limited by the progress of blue-emitting devices,due to the uncontrollably accurate composition,unstable properties,and low *** this article,we add Cesium chloride(CsCl)to the quasi-two-dimensional(quasi-2D)perovskite precursor solution and achieve the relatively blue shifts of PeLED emission peak by introducing chloride ions for photoluminescence(PL)and electroluminescence(EL).We also found that the introduction of chlorine ions can make quasi-2D perovskite films thinner with smoother surface of 0.408 *** is interesting that the EL peaks and intensities of PeLED are adjustable under different driving voltages in high concentration chlorine-added perovskite devices,and different processes of photo-excited,photo-quenched,and photo-excited occur sequentially with the increasing driving *** work provides a path for demonstrating full-color screens in the future.

This paper presents a solution to wireless light control system based on Zigbee. Overall design framework of the system was introduced and analyzed in detail, which contained realization of hardware design. The Zigbee wireless light control system was established based on CC2430-chip of Texas Instruments (TI). In this paper, we achieved designing Printed Circuit Board (PCB) for sensor nodes as end device and coordinator in Protel DXP 2004 and also wrote C codes in IAR embedded workbench development tool to form wireless network. Test results of system show that lights on end device or router in Zigbee wireless sensor networks (WSN) can be controlled by another switch on coordinator, which achieved remotely wireless intelligence light control.
