A microelectronic device that in operation generates or includes component(s) that generate heat, in which the device comprises a heat conversion medium that converts such heat into a light emission having a shorter wavelength than such heat, to thereby cool the device and dissipate the unwanted heat by such light output. The heat conversion medium can include an upconverting luminophoric material, e.g., an anti-Stokes phosphor or phosphor composition. The provision of such heat conversion medium enables thermal management of microelectronic devices, e.g., optoelectronic devices, to be achieved in an efficient manner, to prolong the operational service life of devices such as LEDs, laser diodes, etc. that are degraded in performance by excessive heat generation in their operation. |
