High sensitivity ratiometric fluorescence temperature sensing using the microencapsulation of CsPbBr3 and K2SiF6∶Mn4+phosphor
文献摘要：
A dual emission sensing film has been prepared for colorimetric temperature sensing using CsPbBr3 per-ovskite nanocrystals(CsPbBr3 NCs)and manganese doped potassium fluorosilicate(K2SiF6∶Mn4+,KSF)en-capsulated in polystyrene by a microencapsulation strategy.The CsPbBr3-KSF-PS film shows good temper-ature sensing response from 30℃to 70℃,with a relative temperature sensitivity(Sr)up to 10.31％℃-1 at 45℃.Meanwhile,the film maintains more than 95％intensity after 6 heating-cooling cycles and keeps its fluorescence characteristics after 3 months.The film can be used to monitor temperature change by naked eye under a UV lamp.In particular,the temperature discoloration point of the sensing film can be controlled by the ratio change of CsPbBr3∶KSF to expand its applications.The study of the CsPbBr3-KSF-PS sensing mechanism in this work is helpful to provide effective strategies for the design of reliable,high sensitivity and stable temperature sensing system using CsPbBr3 NCs.
