In order to achieve a teaching materials in the field of atomic physics in senior high schools or universities、 we developed an experimental instrument for observing the laser-induced fluorescence of rubidium atoms using a laser diode. Furthermore、 we developed a teaching material for the photoelectric effect using a hollow-cathode lamp、 which enables the detection of the photoelectric signal without any shading. We measured the work function of cesium atoms and investigated the possibility of the improvements in its performances.
