2025年2月26日 · plqy是产出的光子数与激发光子数(或elqy之电子数)的精确比值。 对于PLQY测试，激发一般选用单色光激发比如激光，通过光功率及波长计算光子数，发射的荧光光子通过积分球收集进入光谱仪系统检测统计出随波长分布的功率进而得到发射的光子数，两者比值即为 ...

2 天之前 · Given the sensitivity of PLQY data to experimental conditions, statistical tools help ensure reliable interpretation. Descriptive statistics, such as mean, standard deviation, and confidence intervals, provide an initial understanding of data consistency and help identify outliers caused by instrumental noise or sample inconsistencies.

2023年5月23日 · 光致发光 (Photoluminescence, PL) 与光致发光量子产率 (Photoluminescence Quantum Yield, PLQY) 是研究材料表征的重要工具，目前材料测试面临挑战有以下三点： (1) PLQY 无法在手套箱内测试。 (2) PLQY 无法进行原位时间光谱解析。 (3) PLQY 红外波段扩展不易。

2025年2月24日 · Organic dyes with photoluminescence in the second near-infrared window (NIR-II, 1000–1700 nm) are promising for bioimaging and optoelectronic devices. Photoluminescence quantum yield (PLQY) is a direct measure of their performance. Integrating sphere technology is effective in determining the absolute PLQY.

Photoluminescence quantum yield (PLQY) is a measure of the efficiency of photoluminescence in a system. It compares the number of photons emitted to the number of photons that have been absorbed. This essentially judges how well a photoluminescent material converts absorbed energy into emitted light.

2 天之前 · Applications of organic luminophores depend on their photoluminescence quantum yield (PLQY). Several strategies have been developed to improve the PLQY of organic solids, and one such method is aggregation-induced emission (AIE). Herein, we disclose a comprehensive study of two molecularly engineered covalently linked isosteric AIEgens, BNTPE-1 and BNTPE-2. The independent isosteres ...
