The present invention provides a phosphor represented by the following formula: K[GeF]:Mn, wherein 0&#x3c;x&#x3c;0.2. The phosphor has a hexagonal phase of a P6mc space group. The present invention also provides a method for fabricating the above phosphor. The present invention further provides a light-emitting device and a backlight module employing the same.

Phosphor, fabricating method thereof, and light-emitting device and backlight module employing the same

A phosphor, having a general formula of K[SiGe]F:Mn. The phosphor is excited to emit a light having a first main emission peak with a first maximum emission intensity and a first dominant wavelength, wherein a relative emission intensity S of the light of the phosphor is constantly greater than 85% across an temperature of the phosphor between 300 K and 470 K during operation, wherein S=(I/I)*100%, Iand Iare the first maximum emission intensity when the temperature of the phosphor is at 300 K and T during operation respectively, and 300 K&#x3c;T&#x2264;470K.

The present invention relates to a differential feedback amplifier circuit with cross coupled capacitors. Wherein, the first and second input terminals of a source follower are respectively coupled to the first and second output terminals of a differential amplifier, and a resistor is respectively coupled between the first output terminal of the source follower and the first input terminal of the differential amplifier and between the second output terminal of the source follower and the second input terminal of the differential amplifier in order to form a feedback loop. In addition, a capacitor is respectively coupled between the first end current source gate of the source follower and the second input terminal of the source follower and between the second end current source gate of the source follower and the first input terminal of the source follower, so as to improve the circuit gain and bandwidth.
