The present invention relates to calibration slides for fluorescence detection instruments and processing method of making them. The aim of this invention is to disclose calibration slides with high photostability and long lifetime for fluorescence detection instruments. The calibration slides are fabricated by patterning calibration spot arrays of modified inorganic phosphors on the glass slide. The process for producing a calibration slide comprises the following procedure : 1) Dispersing the inorganic phosphors of rare-earth doped complex in water; 2) Patterning the affay of the above suspension on the glass slide. The calibration slides in the present invention employ a very stable fluorescing material that is insensitive to photobleaching, has long lifetime and stability under mild storage condition. The calibration slides in the present invention can be used to calibrate and test for some fluorescence instruments, i.e. microarray scanner, fluorescent microscopy, fluorescence spectrometer, fluorescent multiwell-plate reader.
