“Technology media journalists report: Researchers have made significant progress in the field of on-chip ZnO lasing applications. They fabricated a circular ZnO microdisk on a Si substrate, which exhibits a unique toroid structure and supports optically pumped WGMs lasing in the ultraviolet region with a high Q factor. The cavity quality is high enough to support the BGR phenomenon, and the lasing spectrum can be modulated with increasing pumping power.”
“In the field of environmental monitoring, a breakthrough has been made. Researchers have developed a near-infrared responsive upconversion luminescence nanosensor for detecting 4-Nonylphenol, a harmful estrogenic endocrine disrupter. This highly sensitive and selective sensor operates in two linear ranges and boasts a low limit of detection, successfully tested in real milk samples. This advancement holds promise for sensing in food, environmental, and biological samples.”
