Web30 de abr. de 2024 · For “on-off” fluorescent switches, the most common is the binary combination composed by GQDs and metal cations. Many studies have shown that the fluorescence of GQDs can be quenched by metal cation, leading to the formation of “on-off” switch that can be used for the ion detection [19] , [20] , [21] . WebTypical lifetime of a VFD display is 30,000 hours, and the luminance of the fluorescent phosphor (typically 505nm ZnO:Zn) will fade as well as evaporation of the filaments. VFD filaments run at relatively low temperature so I wouldn't worry too much about cycling, but you might want to blank the display and turn the filaments off to save power and prevent …
