Description
[1.マーキング方法]
本発明の実施形態であるマーキング方法では、物品に荷電粒子(荷電粒子線)を直接照射し、これによって生じる非熱平衡過程の反応を利用し、物品内部に周囲とは異なる形態や欠陥を有する発光中心層を微視的な密度で誘発する。
本発明の一実施形態のマーキング方法を実現するためのマーキング装置の一例を以下に説明する。図4に、放射線源として加速器を用いた場合のマーキング装置110の模式図を示す。
上述したマーキング方法を利用して作製される、本発明の実施形態の一つであるマーキングされた物品100から、マーキングを読み取るための読取装置の一例を以下に説明する。
本実施例では、ダイアモンド薄膜に対してマーキングを行った例を示す。ダイアモンド薄膜は化学気相堆積(CVD)法を用いて形成し、その大きさは2mm×2mm、厚さは500μmであった。このダイアモンド薄膜に対し、プロトンを加速して得られる荷電粒子線を走査しながら照射し、マーキングを行った。荷電粒子線のビーム径は約1μm、典型的なビーム電流は50pA、総照射時間は約3000sであった。
本実施例では、鉱物材料である蛍石に対してマーキングを行った例を示す。図10(B)の左図に示すように、用いた蛍石はほぼ正八面体の形状を有し、一片の長さは約30mmであった。この蛍石の一つの面に対し、プロトンを加速して得られる荷電粒子線を走査しながら照射し、マーキングを行った。荷電粒子線のビーム径は約1μm、典型的なビーム電流は50pA、総照射時間は約2000sであった。
本実施例では、リン酸塩ガラスに対してマーキングを行った例を示す。図11(A)に示すように、用いたリン酸塩ガラスはほぼ正方形の形状を有し、一片の長さは約35mmであった。ここで、リン酸塩ガラス上の数字は物理的加工によって刻印がされたものである。このリン酸塩ガラスの一つの面に対し、プロトンを加速して得られる荷電粒子線を走査しながら照射し、マーキングを行った。荷電粒子線のビーム径は約1μm、典型的なビーム電流は50pA、照射時間は20sであった。
