一眼万年，滨松技术工程师铃木健吾和量子效率仪器的20年“情缘”

Core Viewpoint - The development of QY products is a challenging journey, with the reliability of the device being proven over four years from project initiation to paper publication, involving hundreds of experiments, showcasing the engineers' respect for scientific spirit [1]. Group 1: Technical Origins - In April 2000, Suzuki Kengo joined Hamamatsu and embarked on a journey to revolutionize measurement standards in the industry, focusing on optical design despite initial challenges [4]. - Suzuki led the development of the first absolute quantum efficiency testing system, C9920-02, marking the beginning of the application of the "absolute method" [4]. Group 2: Industry-Academic Resonance - The rise of organic EL in 2004 created a demand for measuring the photoluminescence quantum yield (PLQY) of solid-state materials, which traditional methods could not adequately address [6][7]. - Suzuki collaborated with Professor Ando to develop the C9920-02 prototype, integrating a multi-channel spectrometer with an integrating sphere for solid material measurement [8]. Group 3: Market Expansion - The launch of the compact device Quantaurus-QY significantly improved operational convenience and system stability, facilitating its application in the emerging Chinese market for luminescent materials [17]. - A localized service system was established to address challenges in promoting the device in China, enhancing customer trust and understanding of its advantages over traditional methods [18][19]. Group 4: Demand-Driven Innovation - The complexity of luminescent materials led to a heightened demand for measuring upconversion materials, which traditional systems could not meet [21][23]. - The development of Quantaurus-QY PLUS was driven by clear and urgent demands from Chinese researchers, successfully addressing the measurement challenges of upconversion materials [24]. Group 5: Continuous Evolution - The timeline of the Quantaurus series illustrates the product lifecycle, with continuous innovations driven by user needs, including the development of OPAL-Luxe and MINI-PL for next-generation display materials [26][31]. - The rigorous validation process for the C9920-02 system involved extensive testing and cross-verification, culminating in significant academic publications that established its reliability [27][28]. Group 6: Legacy and Future Empowerment - The Quantaurus series has become a standard in over 3,000 laboratories globally, reflecting its impact on the transition from fundamental research to industrial application [30]. - Future developments are focused on higher precision measurement solutions for new luminescent materials, indicating ongoing commitment to innovation in the field [31].
