Controlling light’s polarization at the moment it is emitted is a powerful capability. It unlocks new possibilities in optical displays, quantum information science, and biosensing. At the heart of this capability is chirally selective luminescence, where light strongly prefers one circular polarization over the other. Traditional methods rely on chiral molecules, but their inherent asymmetry is often too weak to be practical. Instead, researchers are turning to a more robust solution. By combining achiral emitters with twisted metasurfaces, they can generate robust, tunable circularly polarized light in ultra-thin devices. That degree of control is only possible through meticulous spatial engineering, guided by thin film thickness measurements and validated through UV-Vis-NIR microspectroscopy. Together, these tools are redefining how circular polarization is designed, quantified, and applied.
Circularly polarized luminescence (CPL) is vital for emerging technologies in optics and display design, but generating it with both efficiency and full-spectrum color remains a challenge. Quantum dots provide tunable brightness across the visible range but emit unpolarized light. Chiral cellulose nanocrystals (CNCs), by contrast, offer a structured, bio-derived platform for controlling light polarization. When combined, they form a system capable of transforming color-rich emission into precisely polarized output.

In photovoltaics, 2D materials, and semiconductors, performance often hinges on what happens at the microscopic scale. As devices shrink and materials become more architecturally complex, microspectrophotometers provide the localized, high-resolution spectral data needed to reveal hidden inconsistencies, validate layer quality, and inform smarter fabrication. They bring clarity to the fine structure of modern materials, revealing how variations at the micron scale can impact overall performance.
Cholesteric-superhelix films have captivated scientists and engineers with their ability to manipulate light in precise and tunable ways. Their complex internal architectures, defined by a hierarchy of helical structures, offer exciting potential for applications ranging from optical sensing to secure data storage. Yet, truly understanding such intricate materials requires a method that can reveal their hidden chiral features without altering or damaging them. Circularly polarized luminescence (CPL) from upconversion nanorods provides a practical method for examining the films’ internal helical formations in detail, offering new insight into how these materials function and respond.
