Summary: Stimuli-responsive smart luminescent materials capable of dynamic color emission with distinct spectral profile/intensity are highly desirable for anti-counterfeiting applications. Here. we report the dynamic manipulation of photoluminescence from metal halide CsPbX3 (X = Br. I) perovskite quantum dots (PeQDs) inside a glass medium by tuning local temperature fields in real t... https://megavitamines.shop/product-category/washing/
