ZnS quantum dots were used as the nanocatalyst. Trace amounts of atropine improved the sensitize effect of ZnS quantum dots. This work is introduced as a new method for the determination of atropine commercial drugs. Detection limit of atropine was obtained 2. Therefore, a new CL analysis system was developed for the determination of atropine. The limit of detection of this system was found to be 2. This method is not only simple, sensitive and low cost, but also reliable for practical applications.

If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. Such a source could then be used to calibrate instruments designed to measure luminous intensity with reference to a specified luminosity function. At other frequencies, more radiant intensity is required to achieve the same luminous intensity, according to the frequency response of the human eye.
A common candle emits light with roughly 1 cd luminous intensity. Prior to 1948, various standards for luminous intensity were in use in a number of countries. These were typically based on the brightness of the flame from a “standard candle” of defined composition, or the brightness of an incandescent filament of specific design. One of the best-known of these was the English standard of candlepower. It became clear that a better-defined unit was needed.
