氟化萤光组成物及其适用之投影机之波长转换装置;FLUORIDE FLUORESCENT COMPOSITION AND WAVELENGTH-CONVERTING DEVICE OF PROJECTOR USING SAME

摘要

本案系关于一种氟化萤光组成物，适用于一投影机之一波长转换装置，至少包含：1个正四价锰离子；以及2.7至7个氟原子；其中，该正四价锰离子系掺杂以作为放光中心。藉由氟化萤光组成物具有良好热稳定性之特性，可达到提高投影机出光之亮度、纯度及投影品质等功效。;The disclosure relates to a fluoride fluorescent composition of a wavelength-converting device of a projector. The fluoride fluorescent composition includes a tetravalent manganese ion and 2.7 to 7 fluorine atoms, among which the tetravalent manganese ion is doped so as to be a luminescent center. By the advantage of thermal stability of the fluoride fluorescent composition, the luminance, the purity and the quality of projection of the projector are enhanced.
