To provide a method of detecting a presence of an object approached to an optoelectronic device.SOLUTION: A method includes step of: (a) providing an optoelectronic device 105 comprising light emission photoelectric elements 405, 3305, and 205, and photoelectric current generation photoelectric elements 404, 3304, and 204; (b) applying an effective inverse bias voltage to each light emission photoelectric element and applying the effective inverse bias voltage to each photoelectric current generation photoelectric element; and (c) reflecting or scattering a light emitted by each light emission photoelectric element by moving an object 21 which can scatter or reflect light or a combination of them to a distance of 0.1 to 5 mm from a point on a front face of the optoelectronic device from which the light is ejected to make the light from dropping onto each photoelectric current generation photoelectric element.SELECTED DRAWING: Figure 4 【課題】光電子デバイスに近接した物体の存在を検出する方法を提供する。【解決手段】（ａ）発光光電子素子４０５、３３０５、２０５と光電流発生光電子素子４０４、３３０４、２０４とを備える光電子デバイス１０５を提供することと、（ｂ）発光光電子素子に有効順バイアス電圧を印加し、光電流発生光電子素子に有効逆バイアス電圧を印加することと、（ｃ）光を散乱または反射することができる物体２１またはそれらの組み合わせを、光が出てくる光電子デバイスの表面上の点から０．１〜５ｍｍの距離に移動させ、発光光電素子によって発せられた光を反射または散乱させて、光が光電流発生光電子素子上に落ちるようにさせることと、を含む。【選択図】図４
