Photoluminescence (PL) is a fundamental optical process that defines how some materials emit light after absorbing electromagnetic radiation. It occurs routinely in the natural world, but experts in the field of photonics have endeavored to recreate and exploit this process artificially for decades. The genesis of two-dimensional (2D) structures like monolayer graphene has opened new

Hexagonal boron nitride (hBN) is a valuable polymorphic material that has been exploited by various market segments for decades, forming the basis of cosmetic products as early as 1940. Large-scale commercialization of hBN products lagged until the ‘90s when synthesis and production processes were optimized to meet growing global demand. The material was revolutionized yet
